Me: “Would you like to put in an email address or mailing address to receive coupons?”

Customer: “Sure, I’ll give you my email address.”

Customer’s friend: “No! Don’t give her your email address. People can hack you and track you down and find you with those.”

Customer: “Oh, I guess I can’t do that then.”

Customer’s friend: “Wait, did you say email or mailing address?”

Me: “Either one.”

Customer: “Well, I can go ahead and give you my mailing address then, can’t I?”

Customer’s friend: “I don’t see why not!”
