I've seen so many drunk elders it's not even funny. One was DF'd after nearly 30 years of the problem being known by the other elders.
Another elder died of cirrhosis of the liver. He and his wife would buy beer by the case almost daily. He also sat on a JC to disfellowship others for doing the same thing him and his wife did. No one ever wanted to talk to him because of his alcohol breath.
