Coffee

A young man just out of college - joined a big multinational company as a trainee.

On his first day he dialed the kitchen and shouted into the phone, "Get me a 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, dumbo?"

"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, you fool?"

"No." replied the Managing Director.

"Good!" replied the trainee and put down the phone!
