They basically have you sign them as if they were a check.
Then they apply it to your account as if you gave them cash....
(it showed as a cash credit on the sheet they slipped under the door later that night)
I can't imagine how they would differentiate between what you paid for with the Funship Dollars and what you paid cash or credit card for.
