Its much worse than that. By not tipping you will inspire (perhaps insure) revenge. If you don't tip well you really do not want to return to the restaurant. Low or no tipping will lead to something disgusting being done to your next meal at the restaurant not better service.
Look at some of the sites where food service people talk to each other:
The Stained Apron ,
BitterWaitress , or
eGullet.

If you are one of those despicable types who doesn't believe in tipping and who frequents the same restaurants repeatedly, I GUARANTEE the servers are doctoring your food or throwing it on the floor and then back onto your plate or worse.

Read the stories of revenge. As long as something disgusting is served to the target, there is no concern that the same adulterated food is served to the next customer as well. That some of the customers are unreasonable, demanding and out of line is clear. The adulteration of their food is still wrong. Yet the servers writing on these sites brag about it.
The stories of revenge inflicted on customers (as well as restaurant owners and management) are enough to make one learn to cook at home.
