They proceeded to quickly recite the Noahide laws and then handed out pamphlets about them before they proceeded to the next car.
I know that you are frustrated by the lack of Jewish missionary outreach to Gentiles - I found this little presentation fascinating.
Usually when Hasids are on the subway they simply ask Jewish-looking people if they are Jewish and then try to give them teshuvah-related pamphlets.
Thanks for sharing that. That is wonderful news!
