Not really

In Poland everybody's minding their own business and we do not greet strangers on our walks or rides. We do not smile, either. It could be perceived by you as rude but we Poles are down-to-earth people, so we address other people only when we need something. However, ask someone for directions, and we Poles turn into the most pleasant people, smiling and helping as much as we can
I am different from most of my compatriots. I often greet pedestrians on MUPs on my rides (especially after they gave me way), which makes them happy and they return their good wishes.
It is different in our community of a small block of flats, where we greet any neighbour and even engage in small talk.
Polish is a complex language.
"Dzień dobry" ( "day good" often shortened to just "dobry!" or "good" -- or even a "-bry!" bark) is just a "Hi" when you enter a place where you are expected to talk (like, a store).
"Dobrego dnia" ("a good day") is a warm form of a greeting:
wishing someone a really good day

How different it is from England, where:
-- Alright, mate?
-- Alright?
