I thought fornicating was having sex out of wedlock. It didn't realize it included having a beer with your mates.Actually it was an honest question, the man enjoyed frequenting bars because that was his reputation around town, and no I don't think it was a rude question and I know he was not kidding in return. He claimed to be "saved." We all have opinions.
He may have been saved. How would any of us know? We could say by his apples, oranges and figs, but we couldn't know that was correct.
Like you said, people have their opinions.
