“Does this shul have a Rov?” “Where was the Rav?”
He was calling the halacha hotline with a pikuach nefesh question that he didnt know how to answer.
Thus both of them werent availabe leaving only the Gedolei haposkim in the Coffee room
Is there some rule that requires someone to say ask your Rav with EVERY halachic question?
Yes we know. always ask your Rav first. (Maybe that could be a sticky)
That isnt a reason not to discuss an interesting question and be exposed to interesting relevent sources.
