A store manager overheard a clerk saying to a customer, No, maam, we havent had any for some weeks now, and it doesnt look as if well be getting any soon.

Alarmed, the manager rushed over to the customer who was walking out the door and said, That isnt true, maam. Of course, well 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 dont have something. If we dont have it, say we ordered it and its on its way. Now, what was it she wanted?

Rain.
