It happens rarely Matt. Keep in mind that they put them is stacks of exactly 20 so they know when 5 are missing. The secret to harvesting is to LEAVE after getting what you need. A few casinos don't even care. Hollywood in Tunica doesn't even keep the chips in even stacks so you can get as many as you want. The casinos that use chip sorters also are easy pickings since most of the chips stay in the sorter. You do need to be carefull and don't ever bring chips back to a table or you may be accused of buying in for a higher price than they went out at. I would also be carefull if there was a player at the table playing for more than the minimum per chip. They will be watching that table more closely.
