Get your head out of the stand.

I find it paradoxical that, in cheaper restaurants, 15% is the norm, resulting in a lower tip for the server. They might not have to perform as sophisticated a service, changing silverware, folding napkins, etc. but the check is usually fairly low. I tend to tip at least 20% at these places for that reason. If my tab is very low, I'll tip at least $3.

In higher priced places, 20% is the norm. If you won't pay that for a tip, please use the cheaper places (Denny's, Red Lobster, etc.).

As you go even higher, the expectation is over 20%.

You cheapskates may think otherwise but you're just being stingy.

That's how I roll.
