I think it depends a lot on where you live in Hong Kong. My parents-in-law live in Shau Kei Wan. It's a slower, more laid-back part of Hong Kong. One of my older Chinese co-workers told me that he considers it "old Hong Kong" and people are much more polite there than where we live in the Western New Territories. I have a friend who is moving from Tin Shui Wai to Tai Po and was really amazed at the difference in vibe and attitude between people in TSW and TP when they were house hunting. She felt that TP was a much more friendly place than TSW. So, there are definitely different feelings between communities in Hong Kong. I've run into a lot of dangerous taxi drivers in our area but when we get really good ones--ones that drive slowly and cautiously we always tip them generously and let them know the reason why. We want to encourage the behavior we want to see and we know that many of the taxi drivers serve the same area for a long time out here. I think that sometimes it's important to hold people to account for their behavior--especially those who are responsible for our safety (drivers) and I have reported dangerous drivers in the past.
