I have a similar one from Fuddruckers. The restaurant had a center island, and the hell spawn of a crotch goblin was running on the counter, kicking shit off.
I said, “Hey kid, get down or you’ll slip and hurt yourself.” Of course his mom starts in on how her precious little sociopath can do whatever he wants and I can’t stop him.
I’m sure you can guess what happened immediately after. It was glorious.
