Why do we tip the mates?

[vinntastic]

Well the mates been eating good I usually go like 60/40 depending but I never give a 20 on a pool, I try to look at it like a free day of fishing,and try to get back what i spent, depends times I would split in half,if pool was small sometimes I give more to them then myself, for instance I won a 145 pool yesterday and gave the mates 70 bucks and I usually offer them water, food, Gatorade,whatever I have that I don't think I'm gonna use I offer,I won pools like 1200 and gave mates like a 400, yeah people get funny when it comes down to the mean green, but I am a giving person and it feels good to no I made someone's day...
