I took a family of four on a dive tour today, worked my arse off toting everyone's gear and sorting out their problems, and I did not recieve a tip. They seemed happy enough with me and all so I'm guessing that either they were cheap bastards (entirely possible based on my brief assesment of the father's moral fiber) or didn't know that tipping is generally expected in this sort of thing. I think I need some sort of tactful or humorous way to let people know that I want a tip. Any suggestions? I've considered writting "gratuities appreciated" or something like that on the bottom of my fin so that they'd have to look at it while following me underwater.
