Who YOU are talking to?

After engineering, a guy joined a big MNC as a trainee.
On his first day, he dialed the pantry extension 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 whom are you talking to?"

"No," trainee replied.

"It's the Managing Director of this company!"

The trainee shouted back, "And do you know
whom are YOU are with?"

"No." replied the Managing Director indignantly.

"Good!" trainee replied and disconnected the phone.
