I have been in china for almost two and a half years and it seems when we got for dinner, I am he only-one who says thank-you to our server. When my Chinese wife's mother does me a favor, I say thank-you, her response is "BuYao" I probably say thank-you to my wife a couple dozen times a day!
So I asked my Chinese nephew who speaks English quite well about it ! He told me close friends and family do not say thank-you, it is understood, you would do the same for them!
He also said you don't thank, those, who are doing their job, for doing their job!
Is this common through-out China or is it by region or city?
My mother was and owner operator of Nursery School in America, please and thank-you were driven into me, like waking-up, it's just auto!
I have tried!!! not to say thank-you but it's like breathing !!
