A store manager

A store manager overheard one of his salesmen talking to a customer.

"No sir,"said the salesman.” We haven't had any for awhile and it doesn't look like we'll be getting any soon."

The manager was horrified and yelled after the departing customer,” Come back next week. We’re sure to have whatever it is you need."

Irate, he turned to his salesman,” Never tell a customer we're out of anything! NOW, WHAT DID HE WANT?"

"Rain,” answered the salesman.
