Old Man Rabbinowitz, known as 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 three pounds of apples, please, and wrap up every one in a separate piece of paper, too." She does.
"And what is that there," Old Man Rabbinowitz asks pointing out a bushel basket in the corner.
"Grapes," says the saleswoman, "but they are not for sale!"
