Why do we tip the mates?

[Honger]

caught a big fish once and was probably leading the pool. One of the mate kept asking me "have you ever won pool before?" more than once during the rest of the trip. I guess i looked like a newb since I didnt have a bib on a winter trip and he wanted to make sure he got good chunk of the pool.

Pool ended up being $300, there were 2 mates so I gave one $80, and the other $80 in plain sight of both of them. The dude that kept asking me the question seemed pissed and actually told me he needs more. I was like WTF, threw him $20 more and never went back to that sponsor boat.

He was probably one in a few but there are times when some of them push the envelope. Ive also seen a mate go around with a jar at end of trips collecting tips. That made me not go on that boat again too.
