That's true, but most churgoers would frown on you knowing that you'd set foot inside a bar. After all they are all above reproach (at least in their minds they are!)
Your prejudice against "most churchgoers" is showing just a little. Most "churchgoers" in the world are Catholic or Orthodox and are not prohibited by Church discipline from drinking (either at home or in a bar). The largest Protestant denomination in the world is the Lutheran Church which, similarly, has no prohibition against drinking, only against drunkenness.
