Getting Even : Part Number 669
Part Number 669
A parts manager for a small repair shop had occasion to order part No.
669 from the factory. But when he received it he noticed that someone
had sent part No. 699 instead.
Furious at the factory's incompetence, he promptly sent the part back
along with a letter giving them a piece of his mind.
Less than a week later, he received the same part back with a letter
containing just four words: "TURN THE PART OVER."
