When walking out of the Wal-Mart after purchasing my things, I walked by the Wal-Mart greeter without showing my receipt to them. I was carrying a small bath rug in one hand and the rest of my things in a bag. She asked for my receipt, and I thought about just walking away and ignoring her, but something clicked inside me and I turned around instead. I asked her, "Why do I need to show you my receipt?" I began to complain that this isn't Sam's Club or Costco where I need to show a receipt to confirm membership and what not, and that it is very inconvenient to the customers. I just want to come in a buy my things and leave in peace, I'm not stealing anything. Then I just left her there and walked away.

Am I the asshole? Should I have just showed her my receipt and been done with it?
