A man joined a big company as a trainee. On his first day he dialed the pantry and shouted into the phone, “Get me some coffee, quick!”
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, you fool!”
The trainee shouted back, “And do you know who YOU are talking to?”
“No,” replied the director.
“Good,” said the trainee as he hung up.
