An cocky young businessman had just started his own firm.
He rented a beautiful office and had it furnished with antiques.
Sitting there waiting for his first customer on opening day, 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.
Talking loudly, he threw huge figures around and made giant commitments. Finally, he hung up and asked the visitor, "Can I help you?"
The visitor said, "Yeah, I've come to activate your phone lines."
Many years ago I was in a busy newsagents, quite a few waiting to pay, a woman dashed in , Oh let me jump the queue, I'll miss my train. One of the customers replied, You have missed it, they closed the station years ago.
That reminds me of something from The Goon Show years ago:
Knock, knock.
"Yes."
"I'm here to disconnect you telephone."
"But I don't have a telephone to disconnect."
"That's quite alright, I've brought one with me."
