The Customer
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."
The manager then 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?"
The clerk answered, "Snow."
