(At the supermarket where I work, we have a store rewards card we can scan if the customer forgets theirs or doesn’t have one.)

Me: “Do you have your bonus card?”

Customer: “No. Could I use the store card, please?”

Me: “Surely.”

Customer: “Don’t call me Shirley!” *laughs* “I’ve waited for years to make that joke!”

Me: “I’m glad I could help you live out that fantasy!”
