Man, I don't wanna spam this thread, but I do have some odd stories after like a decade in the service industry. The last one I'll share for now is the Tale of Mistaken Identity.
Back in college, I worked at a Walgreens that had (for reasons I'm sure made sense to them) a pretty consistent population of homeless people in the parking lot. For the most part they were easy going and didn't bother anybody, so management didn't do much about them, and it was just a Thing about working there.
I had a coworker who had a really dry sense of humor that I got along with really well, and we always liked to make up ridiculous scenarios, so when he came in one day and said the police were looking for me, I thought he was joking. But nope, two officers came back and brought me outside.
Another important background detail was that my sister and I were going to the same college, which was a day's drive from our hometown, and in the winter if she was going back to visit we'd swap cars since mine was a little sturdier. Hers had lots of little pink decorations and flowers and things in it that indicated a woman owned it, I guess, and we'd swapped before that day so I had driven it to work.
Anyway, outside, the cops had custody of an old homeless woman, and at the sight of me she just flew into a screaming rage. "You filth! You philanderer! You fucking brown-eyed Huguenot!" (Being the weirdest thing I had ever been called, I looked it up afterwards, and apparently Huguenots were 16th century French Protestants. THE MORE U KNOW)
The cops asked if I knew her, which I did not. I'd never even seen her in the parking lot before. They led me over to my sister's car, where the lady had climbed up on the engine hood and, according to witnesses, used her wedding ring to carve "BITCH" into the metal in huuuuuuuge letters.
There wasn't much the cops could do other than hold the lady for a day, which I wasn't interested in. I just kind of felt bad for her, so they let her go, and I got to have a very strange phone call with my sister, who thought I was joking. (Of course.)
The funniest part of the story I guess is that my sister is like, a living and breathing saint. She's one of the sweetest people I know. But since we were both poor-ass students, she kinda just let the damage go for a while and drove around with BITCH carved into the hood of her car, to the bafflement of everyone who knew her.
