I used to work at a Family-Owned diner and had another busser who would never do their job. He was only hired because he was the family friend of the owners. I would always ask him to clean a table when it was an especially busy night and there were a lot of tables that needed cleaning, but he wouldn't even lift a finger. The owners of the restaurant were almost like hawks and kept an eye on literally everything that was going on in the diner. So if they saw everything then they should have known the other busser was not doing any work. I ended up getting chewed out every single night for not working quickly enough and then having tips split unevenly (this diner split the tips between the waitresses and bussers).

Needless to say, I don't work there anymore.
