I worked as a waiter on and off for fifteen years. I saw the absolute worst behaviour in people. Bizzarely though, customers who weren't rich often gave good tips, while those who clearly had big bucks (evident by their orders) consistently left nothing.

I worked in retail management for 20+ years. I have encountered all kinds of crazy people with stupid requests. It truly amazes me how these people are functioning on their own in society. I am talking about both sides of the coin as represented here on this list. It's not always the customer's fault and the customer is not always right.

This is far from the first time I have found myself wishing there could be a mental competency exam before allowing people to vote. Also is it really so difficult to remember the person behind the counter is a real live human being? I always greet the person taking my order, even in the drive thru, say 'could I have...' or 'I would like...' instead of 'I want' or 'give me', then I make sure to thank them and smile if it's in person. If it's drive thru or over the phone, I make sure to greet and then thank the person taking my money and the person handing me my food. Empathy is important and it really is not that difficult or inconvenient.

Bottom Line? Rude and obnoxious customers need their butts kicked Out The Door! I'd love to be a manager and toss these losers out. No one should tolerate this behaviours

As a hostel manager, I get the best of Karens. Once I was helping out the reception, and a lady cut into queue, the others gave me the nod, so I started to check her in to get through quick. When she found out she has to take 9(literally) steps to her room,she went nuts and demanded to talk to the manager. I told her it was me. She ordered us to take her luggage upstairs,cause she was sightseeing all day and her legs hurt. When I told her we do not have a porter and she should maybe take one luggage at a time,cause we had many check-ins, she started shouting my head off,telling me I was the cruelest person she has ever met,cause she has cancer and I just treat her badly. I told her,maaaybe we can take the bags up in 20 mins...she kept insulting me, so I said, maybe it'll take 30 mins..or even 1 hour, so maybe reconsider taking those 2 handbags up on at a time. My colleague ended up taking them upstairs in like 10, but I had to take a 3 cigarette break and cry my a*s off quickly and get back to being nice to all the other normal guests. I love working with people,but sometimes I really question myself because of the few miserable people who want everyone else to be just as miserable and break others' hearts. It actually gives me a lot of strength to gather enough money to be my own boss and be able to turn off Karens without being punished by a boss.

I used to bartend for years when I was in my 20s and anytime I got a jerk I would only put alcohol in the straw and not in the drink. It was also my decision if I didn't want to serve someone so that was rewarding when I would kick people out.

Not so much horrible customers, but rather painfully stupid people. Makes you weep.

How about we really f**k with Karens and tell them out the manager wants to speak to THEM.

I feel terrible about what these food service people put up with day after day. But once in a while, it’s a store person who verbally abuses a customer for no good reason. My Mom witnessed this scene years ago in a See’s Candy store: A mature woman was in the store with a pre-teen girl, perhaps her granddaughter. The See’s employee behind the counter angrily told this girl, “Don’t you ever say that again in a See’s store, or I’ll put a gun to your head!” The woman with the girl told the See’s employee, “You shouldn’t be working with the public – you stink!” My Dad jokingly said he should go into the store when the same woman was there and say, “This all looks like a bunch of s__t to me!”

I worked at a shipping store and a lady came in wanting to mail a holiday card to her brother who was slow and needed it to get there next day. I told her well typically same state cards where I live get delivered next day and then I told her that to insure that it gets there next day I suggest fedex next day and it will almost 100% get there. She opted for the regular and cheaper mail option and take her chances. This lady gonna come in and throw a hissy fit because her brother is mad at her because his card didn't get there on the holiday and it is completely my fault and she would've paid the extra money for the fedex.....I'm so sorry but I think I gave you the option lady and YOU chose the cheaper option not me! So this is your problem....I was not sorrythyouproblem

i work at a cinema and a man threw a large popcorn and a pepsi back in my face because HE was late for the movie and blamed me. the lady next in line screamed at me for being to slow to serve her. i love people so much!

I've been working in food service for over 20 years now. Among other things (though I have NEVER physically messed with a customer's food!), one of my favorite petty revenge tricks is in how I ring things up. If a customer orders a chicken strip basket, with a water, and then a milkshake, for example, I usually ring the shake up as the drink with the chicken strip combo, since the water is free. But if they are rude or snarky, I leave the water as the drink, and ring the shake separately, so they pay full price for it. All with the same "customer service smile" on my face. They usually don't realize they're paying about $2 or so more than they should have to. But I know. And, petty as it is, it makes me giggle inside! ;-)

Stories like these just make me appreciate all the people who work in the service industry that much more.

Worked at a concession stand at a movie theater... "Does the butter have real butter in it? I'm ALLERGIC to real butter." I had to go back and dig out the wrapper and assure the person it was soybean oil with artificial flavorings and did they still want it or not? (No, no, couldn't take the chance it was real butter. :P)

Stupid or ball faced theif?

This is why I went from customer service to Geriatric Nursing, dealing with people with incontinent folks with Alzheimer’s & dementia, was so much easier than dealing with the stream of fuckwits that used to come into the shop.

I worked in a live theatre, the show was about to start and a man comes down with his wife to yell and scream about the horrible seats he has, that the girl on the phone told him they were in the centre. Meanwhile, the show is already starting...when he calmed down enough to listen, I was able to check the order and see that he had bought the tickets from the box office at this theatre, and even better...he bought them from me. The wife looked embarrassed and went in to go and watch the show. The husband largely stayed out and sulked. Nice try bud.

Worked in a live theatre, and the show was about to start when a man and his wife came to the box office to argue the seating they had bought. Stood there yelling and screaming at me about how the girl on the phone said the seats were centre. The wife the whole time looked very uncomfortable, and even more so, when I looked at the order and said, not sir, you bought these tickets here are the box office...from me. That sent him into a further rage...the wife went in and watched the show. The husband stood out for a good long time and sulked...ok dude!

Worked as a bartender at a restaurant. Favorite ticket I received from the staff was Hot water No ice.

From time to time, we need someone to talk to. Someone who will listen to us without judgement. https://www.kcrelationshipinstitute.com can help! Whether it be on relationships, personal problems or frustrations.

This just confirms that that the American educational system is complete and utter s**t......
