I also went recently and I thought it was quite a beautiful city.I didn't much of the rudeness, I'm from Mexico(makes HK seems like a paradise)lived there for 15 years, then I moved to Texas(plenty of assholes here also) I've been dealing with rude people my whole life so at this point I just let it pass.
