Server here,I love you. But yeah that shit happens all the time. I work at a steakhouse and a guy came in with his girlfriend and about 8 friends. I took awesome care of them and we had an extra dessert someone accidently rang in so I gave it to them for free since it was his birthday. So all of his friends leave and he stays with his girlfriend. Gives me his check and his girl is like "here you go,but you're gonna take off this steak right?" What? Oh he never got his steak.  I knew it was bullshit,and so did they, but I got myanger to take it off since it was his birthday and we didn't wanna make a scene. Give them their change and got no tip at all. Hate people sometimes. I meet the best people in my town and the worst people working as a server
