I have a group of friends who play Texas Hold'em, and one of the guys who plays has a habit of picking up the deck at really odd times when he's dealing. This is playing with a rotating dealer, so at this time he's a player as well as a dealer.
After the flop, people will be placing bets, going around the table, and then he'll randomly pick up the deck while he's thinking. I really don't think he's cheating or anything. It's probably just a habit, and I'm not sure why it bothers me. Maybe it's distracting? Maybe I'm not able to pay attention to other players because I need to watch the deck to make sure there isn't any funny business? I can't quite put my finger on it.
Is it against the rules for him to do this? I'm thinking the best description is that he's handling the deck when it isn't necessary.
