Deja vu all over again…
I see nothing wrong with saying GS to a member of the opposite gender, but I certainly understand why some people feel it shouldn’t be done.
popcorn:
“In New York when you say “Gut Shabbos” to people they look you up and down and wonder “Do I know who that is” and wonder why I said Gut Shabbos to them…(even to people of my own gender).”
I can’t speak for all of New York, but here in Monsey it’s not like that at all. Everybody says GS to everybody else (to the opposite gender depends on the neighborhood).
