Why should a frum girl expect a frum guy to say “gut Shabbos” to her unless they are the type of very modern people who are not Shomer Negia
What does that have to do with basic menchlichkeit?
Also in Brooklyn men usually don’t exchange gut shabbos unless they know each other.
Then I guess I don’t live in Brooklyn, since I say “Good Shabbos” to men I don’t know. How is it that you know where I live better than I do?
