The regular players there tell each other their hands after they fold to give them extra info. Like when the flop is AA2 they will tell their friends (during the hand) they folded an A so it is more likely they should call raises from another player. I was shocked to hear regs start telling me their hands after I played there for an entire day. They would just whisper to me if they were sitting to my right or left.
The dealers seem great in terms of skill and character!
