The Bread Bag Paradox

(A customer walks up to my lane with a reusable bag. She’s purchasing several canned items and a loaf of bread. I start ringing her up.)

Me: “So, a layer of cans on the bottom, and I’ll put the bread on top?”

Customer: “No, thank you.”

Me: “So, I’ll bag the bread separately?”

Customer: “No, they can all go in one bag.”

Me: “…?”

(I just bagged her items as I initially said.)
