There was many a comment in the latest assembly about not drinking at all "many brothers have decided not to part take of alcohol at all to avoid temptation and so as to not stumble others" we know this is WT speak for "don't drink"
There was also an example of a jw couple who went to a restaurant, they discussed beforehand that they would drink alcohol (who does that?) But when they got there they looked around and no one else was drinking (seriously? ?!) So they decided not to drink after all so as to avoid stumbling the other diners... later they started a study with the chef and he said he had watched them that night and been so impressed at their not drinking that he decided to study... Guess what he got baptized blah blah blah.
There's some serious holes in this obviously made up story, but the message is clear... don't drink oh and also when going to a restaurant only order what everyone else is having (!)
