I leave 20% if the service was acceptable.
I leave less depending on just how unacceptable the service actually was.

If the food is bad, or screwed up, ask the server (or his/her manager) to comp the food. That way, you can still tip the server for his/her service, but the restaurant still eats it for giving you crappy service overall.
TheSmokingMonkey Reviewed by TheSmokingMonkey on . tipping at restaurants... you just had a 100$ dinner... what do you tip, if any at all? just wondering... i can't consciencly walk out of a resturant without leaving a tip, but the wife, on bad service, prefers to just get up and walk out.... even if the quality of food and service was complete shit i just can't leave without feeling guilty if i've left nothing at the table but dirty plates... so do you tip? and if so how much?
