Exactly! So They have to claim the PROFIT...
... ALL those chips will be 'missing in action' and will never be cashed in. PLUS when they do a recall, every has to PROVE where the chips came from. Makes it 'easy profit' for the casino to refuse to cash in chips!
From what you said I won't keep ANY chips I ever expect to cash later! Especially HIGH value chips that would cause attention and the cage to refuse them. NEVER COLOR UP & ALWAYS CASH IN!!
