JWs say they can go anywhere in the world and they " know" that they would be shown hospitality from their fellow brothers. Of all my years as a JW I found this wasn't the case. I honestly believe that if I turned up at any of my fellow apostates on here house and said hi I'm chook can we have a coffee, the response would be how many sugars.
When I was young and moved to different locations and different congregations not all in the same country, I would say that we were shown hospitality in the various congregations. I wouldn't say that this produced lots of friends, I have one or two.
To have coffee at my house would depend on whether the dog likes you
