When I dine out, the waiter or waitress starts on an even playing field of 15%. After that, it's a math game. If they do something above and beyond, or are routinely quick with drink refills, I'll slide them up the tip scale. If they let my drink go empty for more than a minute or two, they lose points. If they bring water right off the bat (practically unheard of nowadays), I add 5%. If they let my cup go empty, and like 10 minutes goes by, and they come rushing back to my table smelling like cigarette smoke, I knock 'em down 5 or 10% (depending on how much time it took). If I have to summons another waiter/waitress for anything, they lose points.
