In the 1970s, I remember being out of town and buying a bag of doughnuts at a grocery store. I walked to the cashier who promptly asked me if I wanted it in a bag. There was a pause and I didn't know how to reply.

Eventually I said, "It's already in a bag."

On another note, there's a hilarious scene of Archie Bunker (All in the Family, also from the 1970s) in the kitchen making hiimself a sandwich and trying to unwrap a single cheese slice. These were relatively new then I believe.
