I must be real strange. I buy in for two stacks, play rows of 3 or 6 numbers (covering about 2/3 of the field) and then cash out. The secret is to not be around when they notice those 7 chips missing! There is always a bank of slots somewhere near to hide behind. Unfortunately my method does not work very well if you want to get all of the colors from a table. It took me two full days (different dealers and different shifts) to get all of the chips (in full stacks)away from the Isle of Capri in Tunica<G>. BTW, I still have full sets of 7 chips to trade if anyone is interested.
