I grew up in a community where everyone said good shabbos to each other. Granted, its a MO community so the men have no trouble saying good shabbos to women and vice versa. As more charedi people moved into the neighborhood, they were the odd ones out who would not say good shabbos. It can sometimes be rather embarrasing if you say GS to someone and they obviously don’t answer back.
Unfortunately, most of the neighborhood had changed to unfriendly and many people did not adopt the “minhag hamakom” to be courteous to their neighbors. Now, very few people say good shabbos to each other, except for people from one shul who still say good shabbos to everyone. Its a shame.
