A man joins a multi-national company as a trainee. On his first day, he dials the canteen’s number and shouts into the phone: “Get me a cup of coffee, quickly!” The voice from the other side responds: “You fool, you’ve dialed the wrong extension! Do you know who you’re talking to?”
No" replies the trainee.
“It’s the Managing Director of the company, you idiot!”
The trainee shouts back: “And do you know who you are talking to, you idiot?”
“No!” replies the Managing Director angrily.
“Thank God!” the trainee says and puts down the phone.
