My two cents as well is, no tipping means no tipping. The possible exception is a couple of times when I have slipped my cabin stewardess a little, for outstanding service, but not always. I like the idea that when the pool waiter is friendly to me, he's doing that because he likes his job and is well-compensated, not because he's ingratiating himself to me. I'm sure it would be different on a world cruise.
