You know, I sure get a lot of receipts. These end up cluttering up the back pockets of my pants, finally (almost always) ending up in the recycling bag at home. Here's the problem: I rarely, if ever, look at most of them. Why do I have to get them? Starbucks and the Cinemark at Valley View ask me if I want a receipt. I always decline, and I can see that the receipt is never printed. This should be the default for the majority of purchases, which I don't expect to take back, especially when you are purchasing things that you can't take back (movie tickets/food, starbucks coffee). When I purchase something large, I will keep the receipt as a proof-of-purchase in case I need it.
I wonder how you could go about getting the lack of a receipt to be the default.
