If this is a pain point for shluchim,
Honestly, I think you'd be hard-pressed to find even a handful of Shluchim that would describe this as a "pain point". This whole thread is based on a single shliach sending a single tweet which was basically terribly expressed bemusement at the fact that people would think a place in the middle of nowhere would have a daily minyan.
I am close with many shluchim in places far more rural or "small towny" and frankly, this whole kerfuffle is a huge joke. If anything were to come from this, I would think better education to the frum traveler community about the role of Chabad and the best ways to ensure encounters are mutually beneficial would be far more important than minyan faqs on websites. I've long had in the back of my mind to make a kind of "visiting a Chabad House" handbook for frum travelers.
