Me: “Your total is $**.**.”

(The customer hands me card, I run it and hand it back to her.)

Customer: “Oh, no! That’s my debit card! I don’t have any money in my account. It’s going to be declined.”

Me: “Well, your purchase went through.”

Customer: “Oh, well, if it went through, that means I have enough money in my account.”

Me: “Well, not necessarily. My brother got himself into a lot of debt by using his cards after he’d reached his limit.”

Customer: “You mean I could still use this card even if there’s no money in the account?”

Me: “It’s possible, but I’m not familiar with your bank system.”

Customer: *to friend* “Do you want to go to the nail salon?”
