Not sure where to post this so I'll just put it here.
Basically, the other day at Uni, a friend and I went into the IT labs to do some important work in the quiet.
We got there and there were these two girls, sitting either side of the room and shouting across a conversation between eachother.
OK, this is blatantly rude, disrespectful and not on.
Thing is, these girls are Asian, talking in their own language and quite clearly talking about us (gestures, pointing, laughing etc).
My friend was upset as she really needed a quiet room to get some work done, so she complained to the IT Technician who said he'd have a word.
Anyway, couple of days later and she's been accused of being 'racist' and is being called up in front of the dean, with the possibility of being thrown off the course!
It's unlikely that any action as severe as that will be taken.
As long as your friend stressed the complaint was about the noise and disrespect, rather than because the ethnicity of the two ladies was an issue, this is likely to go away quietly.
It is their word against yours and your friend's - with no independent witnesses, it hard to see how anything useful could be gained from the dismissal of your friend.
Hope it all works out for you - please let us know.
