Bars are bars. People come to bars to relax, to be a little wilder than they are outside the bars. They come for drinks, smokes, opposite sex and perhaps some actions. People who seek serendipity, proper language and behavior, would have gone to the tea house next door.
So bar-tender, quit worrying. Just keep the liquor flowing and the party going. The meek will never enter, the game, will never be intimidated by the sultry music.
