When I worked in customer service, a guy kept calling in and waiting until he got a woman so he could say vulgar shit. Another guy called me a “n*gger bitch” and he was put on letters only. I know he couldn’t tell what race I was over the phone, but I immediately said “fuck you” and hung up and then proceeded to panic about losing my job once the initial shock wore off. I didn’t lose my job though. 👍🏾

Last place I worked at that actually banned customers was at a pizza place in a college town that did a lot of late night deliveries back when restaurants delivered their own food.

Bounced checks, being rude to employees, not being there when the delivery driver arrived were the biggest ones. After hitting a critical mass on fraternities we started banning the whole fraternity if we ran into issues and they sorted that out fast by getting their members to behave better and other people would volunteer to buy the pizza if the person fell asleep or couldn’t be found. Pretty much everyone who screwed up was given another chance by paying off their balance and the bounced check fee or apologizing to staff.

There was also one guy who never tipped and kept calling and saying is pizza was wrong so the owner made his pizza one night and delivered it himself, then banned the guy when he called and lied about the delivery. He was banned for life along with the people who were racist/sexist. The owner was a jerk when it came to his ridiculous capitalist expectations, but he did defend his employees from external assholes.

Hundreds of gigabytes of horse porn, right in a folder on his desktop called “horse”. The thumbnail of the folder made it incredibly clear what the folder was and what was in it, which was made extra clear by the max zoom his desktop icons were set to. (it was like, no joke, almost 1/10th the screen).

Fun fact: that was the day I learned my state doesn’t have mandatory reporting laws for animal abuse, only csam.

It was the rare occasion of someone being so stupid that they accidentally started their own cell phone scam.

This guy could not decide on what phone he wanted. He had two plans with all of his relatives on them. Whenever someone became eligible for a contract renewal, he would buy himself a phone and give his old one to one of those relatives. He also was very picky, and would try to return his phones for dumb reasons like “I haven’t turned my phone off since I got it, and now it’s running slow.”

He would hop between different stores and customer service to get warranty replacements for his older phones, and exchanges for new ones, and because he was passing phones between accounts, a phone that he had for a year, would look like it was just bought a few days ago, so he would be offered a brand new one, or the option to try another model. When he came into my store complaining, something didn’t seem right, so I spent an entire day researching where all his phones came from and where they went. I discovered that for years, he was costing us thousands of dollars burning through brand new phones and requesting credits for his inconvenience.

The last time we told him that we couldn’t help him, he said he’d never come back, we thanked him.

He touched a waitress in a way she didn’t want to be touched.

He was creepin’ on other customers. When he was asked to tone it down, especially when it came to talking to minors, he got mad and started yelling and shoving chairs.

guy was making threats, demanding to know the full name and address of anyone he talked to, etc. this was a call center job that tolerated verbal abuse of staff and expected us to take it with a smile. it was company policy to not punish customers for verbal abuse and we were not allowed to shut it down. this guy was apparently considered enough of a problem that he was banned from all stores owned by corporate, which I had never seen happen before or after.

Wrked in a bakery with a café part to sit at. the store was in the same building as a convinence store. Every now and then a middle aged woman with smeared make up (think simpsons make up shotgun) went to the convience store the came to us, to first use the toilett and the sit down and “drink” a coffee. at least that is her story. as a worker we all knew that she never drank the coffee, but instead drank those mini alkohol bottles in the toilett ( as if we didnt see the bottles in the trash). she usually gets punch drunk till closing time. but we let her since she obviously felt ashamed about drinking, and seemed to have a hard life as is. but as she got comfortable with the workers, because we were nice to her, she started to belive/act as if she worked there too when drunk. repositioning all the tables and chairs. takeing the toilett keys home and never return them, try to make us hang out inside the store after closing. and if you ever tried to reason with a drunk person you know there is no way. after we needed to call the police the second time just to able to end out shift, and close down, she got banned.

in a way i feel sorry for her, since she was never seen in the store again. these people make me want to be able to help. but i am not able and i get paid minimum wage to keep up with it :/

I’ve a few fun stories.

I spent some years around the turn of the century running a video arcade in a shopping mall. (Kids, ask your parents what both of those were.) Kids regularly got themselves kicked out for violence, whether toward the machines (sometimes hard enough to chip paintwork) or against each other (always fun when a round of Street Fighter results in a round of Regular Fighter.) I once banned a kid who had stolen a roll of prize tickets behind my back while I was reloading a machine’s ticket supply, and very intelligently tried to come back the next day to buy prizes with the still-intact unused roll. I once got a family banned from the entire mall because they decided to leave a scared toddler - maybe five years old, no ability to play the games or money to spend on them, and no discernible ability to communicate in English - alone in the arcade - a dark, crowded, and noisy place with its own open door leading directly to the parking lot - while they went off to do their shopping in the rest of the mall. The kid was turned over to mall security who got the cops involved.

More recently I worked for some years in a 3D-print-to-order factory which I’ll call “Shapeways,” for that was its name. Custom tabletop RPG dice sets were popular items; considerably more expensive than getting a standard set from the local hobby shop, but available in all sorts of bespoke designs in cool materials. One customer was apparently so dissatisfied with their dice order that they not only sent a bunch of Chaotic Evil emails and phone calls about it, but included direct threats to go down to the factory personally to teach us some sort of lesson. This resulted in their account being shut down, authorities getting involved, and the factory hiring an armed security guard for a few months over a set of dice which could simply have been reprinted or refunded. (Shapeways has since shut down, but as far as I know it was not over unsatisfactorily-printed dice.)

One of my previous customers was a mentally ill and delusional elderly lady. She called me about a non-existent plumbing problem in her house, supposedly caused by her neighbor, who she claimed breaks in and messes with her stuff. According to her, everything wrong inside or outside her house was because of her neighbor’s sabotage. She even mentioned plans to kill him. Not exactly the kind of person you want to turn your back on, but also someone who would have been extremely easy to take advantage of. I basically talked her out of redoing the entire plumbing in her bathroom, and we finally settled on me re-aligning her kitchen cabinet doors that - yes, you guessed it - her neighbor had ‘messed with.’

It was quite sad, really. She asked me twice whether I thought her stories sounded crazy, so she was clearly somewhat aware of her condition. I just didn’t know how to deal with someone like that. I refuse to lie, but I also don’t want to tell her she’s losing it. I don’t mind senile people, but I didn’t feel safe around her.

At the video rental store, the customer that returned a DVD case reeking of cigarettes and full of cockroaches. I had seen the customer before and always read the notes about the latest gross ass thing they’d done that flashed up on screen when serving them because all the other staff hated them and would write these complaints. Despite that I didn’t really remember them particularly or have much of a run in with them.

I happened to be the one on shift when they were to discover they’d been banned though. They tried to pick up some movies to rent and I had to explain that I couldn’t rent to them because they were banned. They asked why and I told them that it says here you returned a DVD case full of cockroaches and they responded indignantly “What!? Is that IT!?” They definitely weren’t denying it and seemed very surprised this was a bannable offence.

At my old company we would ban customers that were repeatedly abusive to customer service agents. Agents had the right to hang up on customers that were being abusive and if the same customer kept getting reported, eventually they would receive a letter from the legal department telling them to stop. If it continued, they would get banned.

I remember one guy was so bad that a director got the phone system to automatically route any calls from him to his mobile line and put him in his phone book. He would very politely greet him by name as soon as he picked up the call to make it clear that he wasn’t ever going to get through to anyone else.

I worked at a headshop in the late 80’s amd early 90’s.

We sold nitrous oxide for whipped cream (and to inhale). It’s a very short lived high…mebbe a couple of minutes for the average person. It came in 24 packs of nitrous cylinders for about $50 US.

There was a guy who would come in when we opened at 10 AM and buy a case (144 cylinders) for personal use, and be back in the store before 6 PM to buy another case. Eventually over a few weeks he was buying multiple cases every time. His lips started cracking and bleeding from the cold, and then turning blue. We found out he was going to our other stores in the area and finally banned him.

We had people buy crack pipes and other smoking paraphernalia too, but that one haunted me. I had never seen someone fall that hard into addiction, or that fast. He was obviously miserable and could not stop.

Freelance welding on my days off. A customer wanted to hire me to make a fence gate, but he didn’t have solid blueprints. He had a crude sketch drawn on a scrap of paper, but no specific measurements. I offered to come by and take measurements, but he didn’t even have a fence base to take measurements off of.

Essentially, he wanted me to construct a property fence gate of unspecified size and install it to a nonexistent perimeter fence. I told him these issues, but he didn’t care. He wanted me to build this fence gate, but he didn’t know what size, what materials, and where to install it.

I fired him. A welder’s reputation means everything. I’m not about to make a thing for a customer who doesn’t actually know what he wants. I did him a favor by walking away and not taking his money.
