Sorry for not looking back and closely on Asian, or I'm guessing specifically Chinese, culture. Yes, I think there's truth to what you say about the Chinese especially with entertaining clients.
However, I was refering to day-to-day socialising and maintaining friendships, not professional entertain-clients-to-win-business scenario.
I may be wrong in my observation but I ask/invite Benign (or any other member in Melbourne/Australia) to notice if I may be correct about the mostly Asian crowd at coffee joints and mostly Caucasian crowd at bars/pubs. I know I may be generalising but I believe there is some validity.
