Stingy MFers. Dealers are paid sub-min wage and tips make up the majority of their wages.
Would you seriously want to pass the deal among the players like in a home game? You are probably playing for higher stakes than your home game, so:
1. You probably appreciate having a non-biased party deal the cards (no cheating worries), make sure the pot is correct, read the board, and otherwise run the game.
2. You can utilize all your energy for playing , especially when on the button, where you will be involved more often (or at least should be), without also having to distribute the cards and run the game. Try watching your opponent when the flop comes out if you have to put that flop out there yourself.
