“I bought a doughnut, and they gave me a receipt for the doughnut. I don’t need a receipt for the doughnut. I’ll just give you the money, and you give me the doughnut… end of transaction. We don’t need to bring ink and paper into this. I just can’t imagine a scenario where I would have to prove that I bought a doughnut. Some skeptical friend: “Don’t even act like I didn’t get that doughnut! I got the doc-u-men-tation right here… oh, wait it’s at home… in the file… under ‘D’… for doughnut.”
