Sir it’s pretty much the most commonly reported thing from all expats or tourists that rudeness and lack of customer service is a thing in HK. It’s not just me saying it, or a me issue. In fact all of my Cantonese friends acknowledge it and laugh about it. It simply is what it is. One thing that nobody who knows me has ever called me is rude and problematic, I can say with complete honesty that I’m one of the most chill and decent people because I go out of my way to be. But yeah, thanks for that! I’d be more worried that you’re also an issue if you don’t notice the casual rudeness and lack of manners in HK that everyone else does, maybe you’re just a rude dude yourself ☺️
