A few years ago while traveling in the Northeast, my wife and I stopped in New Haven, Connecticut, at a B&B we'd reserved for the night. No sooner had we unpacked and moved into the living room for tea and treats, our hosts began to talk about religion, and we learned they were Jehovah's Witnesses. I didn't mind so much, but my wife was outraged that our hosts would use their place of business as a launching point to do missionary work.
When they saw my wife was openly hostile to their endeavors, instead of dropping it, they sought to isolate me and ignore my wife almost as though she didn't exist. It didn't matter that she was seething, I'm sure contemplating their demise, they were now focused entirely on me. I didn't want this to go on, so I manufactured a reason to beat a retreat. And we did.
For the rest of our time there we had to avoid our hosts and we took walks and drove around.
Apparently this is considered okay and a great way to spread the word. But what would YOU have done? We were kind of stuck. My wife wanted to read in one of the living rooms but durst not go alone. I finally just asked our hosts to desist in religious discussion and they did, but we were surprised that they would use their B&B to fulfill their weekly stats.
