A young businessman had just started his own firm. He rented a beautiful office and had it furnished with antiques. Sitting there, he saw a man come into the outer office. Wishing to appear the hot shot, the businessman picked up the phone and started to pretend he had a big deal working.
He threw huge figures around and made giant commitments. Finally he hung up and asked the visitor, ""Can I help you?""
The man said, ""Yeah, I've come to activate your phone lines."
