Why do we tip the mates?

[Chico]

The way I answer that question for myself is: When I figure the cost of a fishing trip, I add up all the expenses, from the tip to the gas, rigs, sinkers, etc. I then figure out how many trips I can afford each month or season. Personally I won't cut out the tips just so I can go on an extra fishing trip. But that is just me. I am not a big tipper, but I do try to keep it at 15% of the charter/party boat fee. I go on the same boats regularly and want to keep a good relationship with the crew. If $$ is tight, I would rather skip the pool.
