I know the Wife now she has been here for sometime doesn't like to be only spoken to because of her race/nationality but helps if a person can only be helped by herI wouldn't make a big point when in phill of speaking to someone soley becasue they white or british.
If in phill a brit walked past loads of phills to say hi just to me i'd most likely ignore them unless it was assitance only I as a Brit could give..
