it sorta depend on the circumstances i think.If i just call a buddy and ask if they want to go i don't feel they owe me anything,if they offer 20 then put in the boat.if you are tournament fishing regularly it would be different.I have the boat and the truck,so my partner pays a little more,set up by him.Now he has a boat so if i take mine i put gas in if we use his he puts gas in,we split the truck and entry.
