Knowing that people really depend upon the tourism for their income, I try to tip fairly. I don't always spend that much on drinks and meals out, but what I will do before I go home is seek out a favorite server or barmaid at the beach bar I spend time at and slip them $5, 10 or 20 not for service at that time but "Just Because."

It never hurts to be nice to those who are nice to you.
