Let me make sure I understand the harvesting technique. These markers are placed in the coin slot to warn players not to play the machine because it needs a fill or is out of order. If these are harvested from the machines, doesn't that mean that an unsuspecting player may come along and try to play it? (Or do you request these from the change gals?, etc.)

Of course, I realize I'm asking this question to a bunch of roulette harvesters!
