This happens to me almost daily.

A customer brings up a 1x1 inches, easy-to-hold item to purchase. Surely they don't need a bag, right? After all, the smallest bag size we have would still be way too large for this single item.

With this in mind, once the transaction is complete, I attempt to hand the receipt and item to the customer, only to be responded to with, "uh, can I have a bag??" as if I'm the idiot.

It's like people desire to contribute to landfills.

What's funnier is when it's someone who has a purse on them. You can't put it in your purse?!
