On his first day, he dialed the pantry and shouted into the phone6: "Get me a f!%kin' cup of 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, idiot!"
The trainee shouted back: "And do you know who YOU are f^#kin' talking to, you idiot?"
"No!" replied the Managing Director indignantly.
"Good!" replied the trainee and put down the phone.
