You can also check to see if they keep stacks of 20 in the bank. Some casinos don't bother any more. Also look for places with the automatic chip sorters. They have no clue how many chips are in the machine (well as least normally). If you only take a few you can say that you gave some to the cocktail waitress or just give them back if you get caught. The best thing to do is just play stupid and say that you were going to cash them in later at the cage. I wonder if anyone still has that photo of the chips we got at the first Biloxi show? Shows the damage that a few determined collectors can do in a couple of hours.
