Rake is 0-10% so the rake does tend to cut into the pot more in a 2/4 game than a 4/8 game. I very rarely drink at the table so I dont tip waitresses, and only tip the dealer $1 if it's a small pot and $2 if it's a fairly large one that I win. The players here are supposed to be a little better on 4/8 but I have never played 4/8.
