Typically this, but to a varying degree. If I think the service was good, I'll round it off to a higher number ($20 instead of $15). If the service was bad, $15 or no tip at all. If the waitress is overly attractive and flirts with me, I will give her a $20 tip.

I do not really have a problem with tipping unless the server expects a tip. If they get all pissy because the tip is low, it makes me less likely to tip anyone from the restaurant the next time around (although I will tip them every time after that). I have a problem with people expecting things that they do not otherwise deserve simply because it is the cultural norm.
