Today an older man came through my line. He had done a return at another store of the same company, and said he had credit on his store charge card. No problem...I really don't care as long as your card goes through and is approved. He wanted to make sure he wasn't going to get a bill. Does he not know how credit card work? It ended up being something like he thought he was going to cancel out his return credit by purchasing something new, and that he wasn't going to get a bill for it.. huh? Then after the transaction went through, he noted that the on his card and what his total was from our transaction, was a dollar difference...he wanted to pay the dollar in cash... I sent him to the guest service desk. Enough. I'm still not even sure how this worked out in his brain.
