Me: “And do you have a free rewards card with us, ma’am?”

Customer: “A what? I don’t know. Maybe. I don’t know.”

Me: “If you think you have one, I can look it up by your phone number?

Customer: “My what?”

Me: *louder* “Your phone number, ma’am.”

Customer: “I don’t have one of those! I don’t think I have one! I don’t have a phone number! I don’t have one!”

Me: “Okay, ma’am, that’s fine. Your total today is $26.74, and just to let you know, you could have saved $5.90 if you had the rewards card.”

Customer: “A discount? My phone number is ***-****.”
