I don't know about evil, But if your not in the Bar to get drunk what's the point? nothing can be more boring talking to a bunch of drunks when your sober...
I usually go to a bar to have a drink, or sometimes two. Something expensive that I would not want to pay the $ for the bottle. Getting drunk is not the purpose, nor is it the goal. From time to time there are drunk people who humiliate themselves and their families with their behavior. I guess I believe that adults (I admit the word "adult" no longer has a conotation of "responsibility") who are responsible can go out and have a few drinks and behave accordingly.
