No idle chit chat is allowed. Shuffle up and deal.
Save your drama for your televised tournament play. Some players drive over 60 miles to play, not to hear you moan about your bad cards.
If you don't know whose turn it is to act, it is probably your turn to act.
If you splash the pot, you will cause arguments over who bet what. Such arguments slow down the game and ruin the festive mood of the event.
