It's a Friday afternoon and, as always, Fernando has the free popcorn ready and raring to go for those who would wish to enjoy it. A guy who'd been in the store a number of times in the past and who had, in fact, rented on Fridays previously picks up a couple of movies.
“Receipt or popcorn?” asks Fernando after he hands the man his change.
“Huh?” is the response.
“I've got free popcorn on weekends, if you'd like a bag, and you're always welcome to the receipt of course,” explains Fernando, tugging at the yellow carbon copy receipt attached to the rental slip proper.

“You should have just said that I don't have to take it.” Then, after a brief pause: “But I'll take popcorn.”
