I have had some experiences with alcoholics I do not wish to repeat.
A recent employer was a raging alcoholic, I mean to the point that there were hundreds of beer bottles in the recycling bin, one-liter bottles of expensive hard liquor presented on display in the break room. The only room in the whole office that wasn't totally trashed, held a pool table that no one ever actually used, that had several of the kinds of mirrors that liquor distributors give to bars.
I didn't clue in to this right away. However the guy bet the farm on a technology without looking into whether that technology actually worked. When I had not gotten it working after just two hours, he started raging at me about how it was all my fault that it didn't work. This for a technology I'd never heard of, and would not touch with a hot rock now that I have experience with it.
I finally packed up my stuff, broadcast a terse, angry letter of resignation to the entire company, to the effect that I don't work for alcoholics, then walked out with no advance notice at all.
