Unless you're going to deliver a receipt that matches my meal in value, I don't particularly see the point. I don't want some stock-printed receipt merely intended to impress.

Receipts are just receipts, and there's no real value you can provide for me there. Instead, remember who I am, and welcome me back next time.

I should also note that the author's point could have been better elucidated without relying so heavily on braggart anecdote.
