On his first day, he dialed the pantry and shouted into the phone:
"Get me a cup of coffee, quickly!"
The voice from the other side responded:
"You fool, you've dialed the
wrong extension! Do you know who you're talking to?"
"No" replied the trainee.
"It's the Managing Director of the company, idiot!"
The trainee shouted back:
"And do you know who YOU are talking to, you IDIOT?"
"No!" replied the Managing Director indignantly.
"Good!" replied the trainee and put down the phone.
