Retail/Food Service Horror Stories

As someone who has worked some terrible food service and retail jobs I'm curious to see if any of y'all have some interesting stories to tell from your own experience in these jobs.

I'll go first, when I used to work as a manager at a Domino's I typically worked the closing shifts. This story took place on a Saturday when we closed at 1am. When it gets really late typically the only people in the store are me and 2 delivery drivers and the store I worked at was at a more sketchy part of town.

A guy walks in around midnight, face bloody and shirt stained with blood. He asks if we gave any ice, and after he said that I noticed it looked like he had some teeth knocked out. Of course this being Domino's we didn't have any ice and I was a little scared because this guy looked like he'd been jumped and I was alone in the store at the time (drivers were doing deliveries).

I told him we had no ice and I offered to call him an ambulance but he declined and he just walked out. And I was left kinda stunned but at least he didn't get blood on my floor. That's about it, I have a bunch more stories but I'm more curious about y'alls.
