Haha... what a diff.... 
You mean you didn't know?
When poly / uni students go for attachments, 90% of the time,
they are regarded as cheap labour and used to do the mundane stuff
that regular office workers don't want to do.
Yes, that would be filing and photocopying things.
The other 10% of the time, they will be given some "regular"
work to do.
The company is smart enough not to make the attachees do 100%
filing.
That's because they don't want to lose this cheap source of
labour should the attachees complain to their poly/uni about the
crap work they do.
