When you make a purchase, then toss your receipt or refuse to take it from the cashier, you have NO right to get pissy at a store who won't refund or replace your questionable goods without your proof of purchase.  It doesn’t matter that you were "just in a little while ago" if you cant prove it.  Make a little effort yourself to safeguard your purchase by hanging on to that little piece of paper for at least a day or two—stop blaming someone else for your failure and don't be so nasty to employees who are REQUIRED to have proof of purchase before issuing refunds or returns. — I GAVE YOU THE STUPID RECEIPT—YOU THREW IT OUT IN SECONDS
