Joke to share...

A man joined a big Multi National Company as a trainee.....
On his first day, he dialled the kitchen and shouted into the phone:
'Get me a cup of coffee, quickly!'
The voice from the other side responded:
'You fool; you've dialled the wrong extension! Do you know who you're talking to?'
'No' replied the trainee.
'It's the Managing Director of the company, you idiot!'
The trainee shouted back:
'And do you know who YOU are talking to, you IDIOT?'
'No!' replied the Managing Director angrily.
'Thank God!' replied the trainee and put the phone down.....
