Lol...in the country I come from, we actually take a moment to greet & ask after folks' health. People take a moment to listen and form a reply which can sometimes also be a long winding one :3

Where I live now, it's interesting because even before you ask a how are you in response to their greeting, they are already replying with an automatic "Good, thanks." and turning away. Body language cue : pleasantries are over...now get on with life.
