Carl, I walked with 20 blue. It is easier to harvest 20, than 2-or3. They most of the time won't notice if even stacks appear, but with a couple missing from a stack bells go off. Ofcourse you must have a busy table. I got 60 yellow from the Hard Rock while at last years convention. A new Rou. player just got up with 60 chips and left the table, I heard him ask where the cashier was, I then said I would cash and gave him 60 bucks. He got up when the dealer and supervisor where talking and left right under their noses, I couldn't believe it. Noone else at the table. Only in Vegas, a true story.
