Customer mad that I was taking too long in the restroom
I wasn't even on the clock. I was using the restroom before I was about to return from my lunch break. There are only two stalls in the restroom, but there wasn't even anyone in the other stall! But this stupid lady assumed that both were occupied or just didn't want to go in the other stall for whatever reason. I don't know what the hell her problem was, but as soon as she walked in the bathroom, I heard her sighing, grumbling, and saying "Jesus". Then she waited outside the stalls and I suddenly heard her mumble (but definitely intentionally loud enough for me to hear), "it shouldn't take that long to pee." I mean, I actually was doing number two as well, not that it was any of her business. And for all she knew, I could have been taking care of "girl stuff" too, and obviously she should know that, being a woman. I definitely gave her an incredulous/dirty look as I came out of the stall. I wasn't on the clock so I wasn't being paid to be nice to her!
