A store manager overheard a clerk saying to a customer, "No, ma´am, we haven´t had any for some weeks now, and it doesn´t look as if we´ll be getting any soon."
Alarmed, the manager rushed over to the customer who was walking out the door and said, "That isn´t true, ma´am. Of course, we´ll have some soon. In fact, we placed an order for it a couple of weeks ago."
Then the manager drew the clerk aside and growled, "Never, never, never, never say we don´t have something. If we don´t have it, say we ordered it and it´s on its way. Now, what was it she wanted?"
