I guess it all gets down to why someone gets into the jackpot to begin with. If your intentions are to win money then giving all to the crew is not for you. However if your intentions are to give the crew a larger tip than you could normally afford then giving it up is what to do. You dont have to be a regular on a boat to want to extend a thank you to a crew. It gives me a very good feeling when I can hand a crew member $100 or more dollars on a short trip. I'll bet if this was the norm, crew members would go out of there way to give it there all. I say cut them some slack and give them the pot.
