My wife drinks very very little if at all. I can't actually remember the last time she had a drink. If she did drink, I wouldn't mind anyway. It actually causes me concern if I meet someone somewhere and they opt out of having a drink out of deference to me. I would actually prefer they don't modify their choices just to please me, if anything I would be pleased if they did drink while I have my coffee! I'm whole enough in my sobriety that I can see that while I can never drink again I don't have the right to prevent anyone from enjoying a drink.
Having said that, I avoid messy drunk people as they remind me of how I was.
