There is a fairly large subset of Americans who will tell you that Chinese people are highly respectful, rule following, group oriented, clean people. The first thing that most people realize though when coming to Asia is that those Americans are stereotyping Asians based on Japanese culture. I spent my first year in Asia split between China and Japan, and I remember my most distinct impression being that the two countries tried their hardest to be as different from one another as possible.
I just moved in around the corner from a 7-11, and my I noticed in my now increasing visits that there is something distinctly unnerving about the atmosphere in there. The store is set up for Japanese people. Most noticeable is the mass greeting whenever someone enters the store (which I always found unnerving in Japan), but also the food is similar (less sushi and more noodles, but both places have both), and they even serve Asahi beer. While an Asian 7-11 is far different from an American one, it does seem the management of 7-11 has stuck to a single formula for the entire region.
Its been fairly well proved by this point that matching a local service culture makes a huge difference in the success of international consumer good companies. Wal-mart was famously unsuccessful in Europe, while there have been studies published showing that Indian people actually prefer a chaotic market to an orderly supermarket.
China's service culture is something of a mystery though. When I first was in the country salesmen either gave you a hard sell or completely ignored you, more and more they seem to be reaching a happy middle ground, still somewhat lazy service, but one where you can get what you want when you want it, and pick up on the character of some of the underpaid staff. Chinese people seem to like it fine enough, as most will admit that they like a bit of renao (noise), but on the other hand places like 7-11 have done quite well, and restaurants still try to force their workers to exercise in lines every morning despite high-schoolish protestations. And every multi-national seems to think China is like a more cost-conscious America.
Personally I'm for a bit of a human touch in marketing, which a Chinese restaurant sometimes has a bit too much of, but it can be quite rewarding at times. I don't think the real Chinese service model has been discovered yet though, but whoever does discover it will make a fortune.
