My live table persona is such that I want everybody to like me. And it is easy to do when I'm winning. Just being talkative is pretty much enough for me. When I'm on tilt I'm such a jerk though.
Anyway, this isn't unheard of. Sometimes I'll even play in the side-bet game that my neighbors make up. "First person to show a duece gets $1 from each player. If you win the pot with a deuce you get an additional $1 from each player, per deuce", etc.
and players frown on this, and it's certainly a tell when player A mucks his hand and picks $1 from his two friend's stacks. "Well damn. There goes one of my outs for 22." Expect to get dirty frowns from this player as he mucks preflop to see the case deuce land on the flop.
