I think there's a lot of establishments that forget that tipping is not a mandate. It's a courtesy and it should be based on your level of courtesy to the person that you are hoping to receive courtesy from. For me, no courtesy given, then you're not getting that courtesy. Beyond that, the wait staff needs to be pissed off at the restaurant owner for not paying enough.

Only exception to that rule would be Dick's Last Resort, but their schtick is being rude
