Can a pawn shop in Arizona hold an item I pawned on one ticket to use to pay on an item they lost money on from a different item I pawned?

To frame this question in a different way, imagine that the statutory date for redemption of your pawned item has passed and the pawn shop refuses your late tender, without giving a reason. I think you would agree that they are absolutely entitled to refuse your late tender and the statute gives them the right to retain the item once the redemption period has expired. Now change the facts just a bit and imagine that the moon is blue and they refuse your late tender because the moon is blue. If they are privileged to refuse your late tender for no reason at all, why would they not be privileged to refuse to take your money because the moon is blue? The point here is that the statute gives them the absolute right to refuse your late tender. They may refuse it for a good reason, a bad reason, or no reason at all.
