What is the worst restaurant related experience you’ve ever had?

Had a server at a local place we check out a few times a year clearly doing some sort of hard drug between talking to us.

Seemed normal when she greeted us, then was falling into walls, grabbing random plates we were eating from, tripping, closing their eyes while mumbling/talking, it was sad. Think it was Heroin, but can’t say for sure.

Didn’t go back there for a while. Employee still works there and I hope she doesn’t remember that.
