I get this question now and then. " I how much should I tip you ? "
I dont answer it actually. I tell them that if they are served well , have a great day on the water, they had fun and caught some fish. A tip is nice for a number of reasons. I would rather the customers keep coming back one or two times a year with an average tip or no tip. If they come back, they had a good time. It is only up to your discretion. I would say the best tip I remember was to a guy I ran charters for when I first started. A customer he had from Washington state came to fish for a couple days and the tip was a 7ft custom made St. Croix fishing rod. Sometimes a box of beer or some home made fire water.
Just have a fun day and show your appreciation if you do well and have fun.
