[Greg Needel]

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 money and you give me the doughnut. End of transaction. We don't need to bring ink and paper into this. I can't imagine a scenario in which I would need to prove that I bought a doughnut. Some skeptical friend... don’t even act like I didn't buy a doughnut, I've got the documentation right here. Oh wait, it's back home in the file... under "D", for doughnut.
