Just Send It To Every Email Ever And It Will Find You

(Our registers have recently added the option of an emailed copy of customers’ receipts if they would like it; we are required to ask each customer at the end of their transaction.)

Me: “Would you like a printed receipt, emailed, or both?”

Customer: “Oh, emailed.”

Me: “Sure, can I get your email address, please?”

Customer: *suddenly hostile* “I’m not giving you that; you’ll send me spam!”

Me: *puzzled* “If you want your receipt emailed, I’ll need the email address to send it to.”

Customer: “Well, can’t you just send it without me giving it to you?”

Me: “Erm… no.”
