A young man joins a big corporate empire as a trainee. On his first day of work, he dials the pantry and shouts into the phone, “Get me a coffee, quickly!” The voice from the other side responds, “You fool you’ve dialled the wrong extension! Do you know who you’re talking to, dumbo?” “No,” replies the trainee. “It’s the CEO office, you fool!” The trainee shouts back, “And do you know who you're talking to, you fool?” “No,” replies the CEO office indignantly. “Good!” replies the trainee, and puts down the phone immediately.
