Some years back a trainee accountant joined the headquarters of a large firm. He was a graduate of a top University and thought rather highly of himself.
On his first day he dialled the canteen and shouted into the phone, “Get me some coffee, quick!”
The voice from the other side responded “You fool, you’ve dialled the wrong extension! Do you know who you are talking to?”
“No”, replied the trainee.
“It’s the Managing Partner, you fool!” The voice shouted back.
The trainee did some quick thinking and asked forcefully, “And do you know who you’re talking
to, you fool?”
“No”, replied the Managing Partner.
“Good”, said the trainee as he hung up.
Just as well this was long before we all had trackable direct dial extension numbers and caller display!
