If you do not come back....
then the seat is considered empty and your money is automatically credited to your card/account.It all works out...no problem The floor staff then fills in your seat with another body and you go onto a waiting list if you do not return on time. Happened to one player who was up about $700 in a $1-$2 game. He took too long(maybe 5 minutes)and his seat was filled by another player,so he had to go on the waiting list and the wait was for about another 1 1/2 hours. He was not pleased(he had played most of the day and was way, way down and the $700 was almost getting him back to respectable loss levels). But...that was/is the rule.
