Hey Jim... Might the lady have been freaked out not because of AA anonymity, but potential HIPAA violation? The guy at that point was a patient at this place, yes? So by calling your friend and saying "There's somebody in here who lives near to you, can I give you his number so you can help him out", assuming the guy had not given you the ok first, that could violate his right to confidential treatment. Because even if you had not told your friend this man's name, the fact that he lives near your friend and is in detox is identifying information. The point's moot if he told you it was ok. Anyway. Food for thought.
