You may not know this, but it's very easy to return things to the grocery store. I don't do it that often, but it's amazing what reasons they'll accept and refund your money. That’s what the service counter is for.
Spoiled food that you are holding in front of them is Beginner Level Returns. I like to think that many years ago, when I successfully returned a $7 watermelon for which I had only the receipt in hand, was at least Advanced Intermediate Level.
