I take it that you are from a faith that believes that drinking an alcoholic beverage is a mortal sin. I am not. That said, I don't believe that anyone you'll find in a bar is necessarily more sinful than the average person you'll run into in public. I'm not as optimistic as you are that people usually find their way to God, but I don't think people who frequent a bar are in any particular danger just by being there.
Absolutely not! I love to drink wine...
I am saying people that hang out in Bars where the clergy attend our proably too looped to learn anything about Jesus and his message....
