premise: Verdict : Make sure the credit cards in your wallet are yours . Check the name on the card every time you sign for something and/or the card is taken away for even a short period of time . Many people just take back the credit card without even looking at it , " assuming " that it has to be theirs . Why would someone intentionally hand a card to a customer that was not the customers ?
hypothesis: If the mistake is unnoticed , the worker can use the card later .
