My sister-in-law worked for a Japenese firm in London, they all spoke in there own tongue, excluded her from any social events and made life so awful for her she was forced her to leave.

I have a Jap working for me and she is very dedicated and loyal, she told me she'd never go back to Japan as they treat workers and foreigners terribly.

That said, the Irish are the most racist in the world without a shadow of a doubt.
