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..... :D
