Here's one...
I used to work at UNO's as a server. Our uniforms looked like this:
So I was serving this one couple, and I could tell when they arrived that they had already consumed a few drinks. They were being pretty obnoxious. The girl ordered her steak medium, and she said it was medium well... it was medium. She was being a real bitch about it, and I apologized and told her I'd get another one out to her quickly.
As I turned to walk away, she said to her significant other, "Maybe if she was smart, they wouldn't dress her like my 5-year-old nephew."
Awesome.
