If he is a jerk or don't give you water to fish then i would consider that. in most of these type tourneys you are an observer that can fish. I wont ask for gas money from my non-boater but in another circuit i am a non and I will offer it. also keep in mind the big motors today don't eat the gas like the old one do. HOWEVER if he puts you on fish or you get a check he should not be stiffed.
