I think if a waiter or waitress kept touching me I would tip less.. I really would see that as an invasion of personal space. Also, if some waitress kept touching my boyfriend.. Three pennies = TOO MUCH!!!

my bf and I have been known to tip like 25-30% because of the service. I LOVE it when servers memorize what you order, get it right, and then serve the dish to the right person. I find that very impressive. The one waiter we had that got the high tip did this, and we were constantly asking/changing something, like white onion instead of red, fries instead of something else, etc etc. He didnt mess up ONE thing! Also, he would bring us fresh drinks before we had even finished the last.. he said "I noticed you were getting low on your drink." It was a really nice experience.
