Unexpected Comeback In The Bagging Area

I’ve just moved to a new neighborhood, and I’m walking into the local grocery store for the first time. As I’m passing the checkouts, I overhear:

Customer: “Well, the customer is always right, though, so can’t you just do it?”

Cashier: *Unbothered.* “No. Even if you weren’t deluded, the computer won’t let me authorize that.”

I think I’m going to like shopping here…
