I worked there with Chinese dealers & I had to deal with Chinese gamblers. I tried very hard to be friendly to them too. All sorts of people gamble you know from Rock Stars to the homeless.....your point is? Why shouldn't I expect them to have manners? Not to be rude & have some common sense where they spit.Call my old fashioned, but I don't expect to meet the best ambassadors of a country in a Casino. IMO you have to be very selfish to be a gambler. Selfish enough to ignore the rules of the country you're visiting/living in.
