I was just on a trip and the dive shop owner took all the tips and said, "we will distribute, don't you worry". I don't know if my money ever made it to the workabees.
A few years ago I was finishing up a week of diving. There was 2 dive helpers( not sure what they really were, but they helped out). One of the helpers said he was the head of the group, so I gave this guy the tip and said to spread it evenly. As I was walking out, I saw the other guy and said thank you and I gave your tip to the head guy to split with him. He thanked me and than ran after the other guy to start a fight. The other guy lied, there was no lead and going to steel the money.
