I live in a smaller town (12k people), and most all of the restaurants I eat at are NOT chain establishments.
I always try and leave 25% minimum, but usually more. For example, went for lunch Friday and my total was $17, I left a $7 tip (40%). I do this because I know I'll be back, and I don't mind leaving a couple extra dollars if it gets me great service every time.
Truth is, it would probably be good service even if I didn't leave much of a tip. But the staff is always polite, remembers what I ordered last time, etc... I consider it a way of saying thanks more than anything else. And besides, if they are waiting tables, they probably need the money more than I do, that's how I look at it.
