A picky customer comes to a small food shop and sees a new delivery of fresh fruit. “Give me two pounds of oranges and wrap every orange up in a separate piece of paper, please,” he says to the saleswoman.
She does.
“And a pound of cherries, please, and wrap up every one in a separate piece of paper, too.”
She does, although frustrated with the demand.
“And what is that there,” he asks pointing out a bushel in the corner.
“Raisins,” says the saleswoman, “but they are not for sale!”
