I'm a cheap SOB, so i look at it this way. if I get good service as in I was served as well as i expected without any problems, I tip 15%.
if the service was less than satisfatory, they get less. If they piss me off or i have to wait a long time, they get a penny.
if they go out of their way and give exceptional service which makes my dining experience special, I'll tip up to 25%.

what drives me crazy is this tipping thing is getting out of hand.
At a local donut shop i go to every morning for a cup of coffee, they have a tip jar on the counter. WTF? A tip for selling me a cup of coffee across a counter? NFW.
