Taking guests on your boat.
If I call someone and say "I am going out- Do you want to come along?" I expect nothing as I asked them to come along. If they offer, great, if not, great-I was going with or without them. If I am asked along by another I always offer something in return-That is how I was raised and what I believe in. I have fished with others who invite themselves along or beg to go fishing and offer nothing. After a couple of trips like that, I won't take them again.
I have a friend who offers to chip in every time, even though he knows I will say don't worry about it. He has gotten wise and brings food and beverages, or bait, or beats me to the launch fee envelope, or pays for the gas when ever he can beat me to the cashier.
On the other hand, I have a brother-in-law who used to invite himself and never chip in, and he no longer gets sets foot on my boat.
Those who run their own boats and fish with friends or others on another boat, definitely are better about chipping in as they realize the associated costs.
One was someone I'd met thru LL and fished with only that one time. He PM'ed me later saying he forgot to pay.
Another was a co-worker of my wife. I used to take him out once every year during the spring walleye run. One year we didn't catch many fish and he "forgot" to pay. Gas to the river in my truck is $40 plus boat gas and bait. $25 isn't too much to expect...I said something to my wife who said something to him. He finally kicked in but did mention that we didn't catch many fish that trip. Apparently he didn't feel he'd gotten his $$$';s worth. BTW,he lost a bunch of my hair jigs...We looked at it differently: He thought of it as a cheap guide trip with a no (limit of) fish,no pay. I looked at it as a favor to someone who didn't have a boat.
Another was a friend on an agreed-on trip to 'Bago. It's about 150 miles round trip....He was kind of jealous that I caught an almost-new fishing rod on a reef an hinted that since I had a ton of rods and don't use lower-end gear maybe he could put it to better use...It's irrelevant but He earns a lot more money than I do
I have not fished with any of them since those particular trips.
I have other friends who I'd pay the whole cost for a cross-state fishing trip.
If I feel I've been deliberately taken advantage of - whether fishing or anything else - I reduce or eliminate contact with that person. I have no tolerance for folks who callously use others.
Fishing a hot bite from anywhere 5-7 days straight can get kinda expensive and I think it's only fair that the person who is fishing with you shares on the expenses. The guys who I have fished with in the past and never even offered are left at home to read my fishing reports .....
Unless its a big trip. Then I will say right up front, do you want to go fish XXX and split the gas? If they say yes, then I expect gas money.
