this woman brings me her items, her reciept, and the sale tag from the sales floor. she tells me she got mischarged for two of her items. i try to quickly adjust the price, the register glitches and instead of giving her a refund total, tries to charge her $1.06. i call over the supervisor who said he had the same problem and instead to ring it in as a coupon. well something about that pissed this woman off so much she returned everything she bought telling me we were wasting her time. i told her she was wasting the food cause we had to defect all of it out. stupid.
