I havent heard of that one... but I dont have much live casino poker play either, that sounds like a good rule to me
But like I said before, I would rather not have just sat down at some table, then see some other guy come in with some huge amount of chips and basically start buying pots left and right.
Again, to me, the person trying to bank money is really doing himself a disservice at a table, and even though it is frustrating to see someone win a big pot with all your cash and then take it off the table, at least he is coming back and at a disadvantage as well, at least in my opinion.
