I returned an item to a store for which I had paid for with credit card. They refunded me in cash. Im now realizing that maybe it’s a problem since a store pays a percent for cc payments. Do I have to return to the store and make them aware? Do I owe them the percent? (The cashier was the owners son whose a highly functional down syndrome. If that makes any difference. Maybe he didnt pay attention to the form of payment)
Many stores know this and nevertheless return cash to their customers, and it serves them in a way that they show themselves as having an easy return policy. If the store didn’t ask that you return the difference, or even if the store put a cashier there who didn’t say it, that is their internal issue and you don’t have to worry about it.
