Trainee
A man joined a big multinational company as a trainee. On his first
day he dialed the pantry 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?!"
"No," replied the trainee.
"It's the managing director of the company, you fool!"
The man 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
