joined a big Multi National Company
as a trainee
On his first day, he dialed the kitchen and shouted into the phone
: "Get me a cup of coffee
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 kept the phone down
