I remain pretty dubious about generalisations about the populations of countries as a whole. In my experience, these sorts of differences are more local. People in city centres are less friendly, because it's an intimidating environment. Walk your dog out in the 'burbs or a park somewhere and people are far more likely to be relaxed and say hi.

Yes but I'm not talking about saying hi to any person in the city center.

I'm saying about people you see daily (like people in a reception) not saying hi/not acknowledging it when greeted (amongst other things). It's weird

Or someone starts a conversation then the conversation dies suddenly and that's it.
