A few years back I was in such a place where gut shabbos is exchnnged betwenn both genders and it was abundantly clear to me that some girls were flirting with their enthusiastic good shabbos and with their coy smiles. As for the guys they were only too happy to say good shabbos to attractive dressed up girls.
I’m so glad you brought this to my attention. It just so happened that, as I left lunch today (at Bravo Pizza, in Manhattan), a frum woman approached me and asked me where 36th Street was. Having seen your advice before lunch, I was prepared for this flirtatious assault (there’s no way for me to know if she 100% lishma in wanting to know where 36th Street is) and promptly and wisely ignored her and walked away without saying a word.

(No, not really. I actually had the shameless gall to actually tell her where 36th Street was.)
