as i am going anyway i dont ask for anything and if they offer i tend to say dont worry about it but if they insist i tell them 20 or 30 dollars,but its also good if i pull into the servo and they say i will get the ice or any nibblies for the day,also i aways feel if i go with anyone else that i dont give enough money so i hope i do the right thing when out in someones boat.brad
