A man joined a big multi-national company as a trainee. On his first day, he dialled the kitchen

and shouted into the phone, “Get me a cup of coffee, quickly!”

The voice from the other side responded, “You fool; you’ve dialled the wrong extension! Do you know who you’re talking to?”

“No” replied the trainee.

“It’s the Managing Director of the company, you idiot!”

The trainee shouted back, “And do you know who YOU are talking to, you IDIOT?”

“No!” replied the Managing Director angrily.

“Thank God!” replied the trainee and put the phone down.
