Trainee

A man joins a big corporate empire as a trainee. On his very first day of work, he dials an extension and shouts 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. "I'm the CEO of the company!" The trainee shouts back, "And do YOU know who YOU are talking to?!" "No." replied the CEO indignantly. "Good!" replied the trainee, who put down the phone.
