COMMON COURTESY OF HONG KONG
After living in Hong Kong for nearly 7 years, I think that I have seen it all in terms of lack of manners, politeness, social skills and inadequate behaviors. I could write a whole book about it. Yet, instead I will just share with you a little drawing of my composition that resumes quite well the 4 most irritable things that are part of the culture and the traditions and thus people's everyday life in Hong Kong. And if you try to say something they will usually give you a startled look as an answer as for them it is perfectly natural and they do not see any problems doing it to your face. Common courtesy is not a thing in Hong Kong, and you better get used to it if you want to survive this concrete jungle.
Try to live with all the above (and much more).... everyday....
