Thanks for the responses so far.
This person received counsel years ago (when they were served alcohol when underage, but married, in their own home ), but no warning specific to alcohol since then-- however, the elders are telling them that since "several warnings" have been given, it is now a JC matter (even though my friend cannot think of when these other warnings ever occurred). They have not had a drink in months.
Needless to say, this area is no stranger to liberal use of alcohol (by EVERYONE).
