do you tip at resturants?

I have to agree with Longgone and Fastback340.
Waiters and waitresses don't make much and depend on tips.
If they do a good job I give them a little extra. If not they may get less.
If they're rude or don't show up to see if everything is ok I'll probably
have a talk with the manager.
Yours did sound like a jerk though. He's one the manager should have heard about.
