On another thread many made the comments that the congregations not in the United States seem to have different rules than elsewhere, and also more freedom.
I suppose that makes "elsewhere" = the US of A...
From (1) what I am reading on this board and (2) my JW memories from over 20 years ago, I doubt this is true as a general rule. Of course everywhere there are more or less strict interpretations of WT instructions by different bodies of elders, and there might be national nuances according to the branches, but the room for difference is very limited (unless the difference is part of the NY policy, e.g. Mexico vs. Malawi, the blood official stance Bulgaria, etc.)
Do people in other countries think of it mostly as an American religion?
YES. Everybody does except JWs.
We had a pioneer sister that went to France to visit and was invited to pioneer school while she was there. She said one day as they were about to go out to service someone opened a bottle of champagne and they all had a drink before going out to field service.
LOL, Champagne is something pioneers can rarely afford (but are sometimes offered).
I grew up in a wine-producing area (Beaujolais) and the general unwritten policy was not to accept a glass of wine during FS, except at the last call.
Otoh there was wine at the Bethel table (also in Italy and Greece I was told) but this was Brooklyn-approved.
