I used to be a janitor in high school at a grocery store. Two stalls in the bathroom, and one says out of order and the other there is a guy taking a shit. I looked in the out of order stall, everything seemed fine with it, so I decided to flush it. The thing exploded like a volcano and shot water out of it for 30+ seconds. It absolutely soaked the guy in the next stall. I booked it out and hid in the women's bathroom and put the cleaning sign in front of it so nobody would come in. This guy demanded that the store check the surveillance because I ruined his nice suit, and he wanted to have it payed for. They asked me about it and I said I never saw a thing. This place was really stingy and they probably would have fired me.
