Lydy's Anarchist Revival Meeting

For normalization purposes, I would like to check whether you would find the conduct of the people working at my local post office to be New York-polite. (I was just there and thought of this post.) They stare deadly past you, making no personal contact at all, to you or anyone else. I think they mutter "canihelpyou" and "thankyouhaveaniceday" at the appropriate times. They don't do anything unambiguously rude, and they do provide the services that you ask of them. Does that make them polite in other parts of the country, or do we mostly agree that they are not very friendly?
