Have you ever been asked one? I have, many years ago when I returned to work after my husbands funeral, the office lothario who was in his fifties, ugly and dribbled asked me "Does this mean you are now available?" I can't remember my reply (It was 24 years ago) But it was very withering.
Inappropriate questions, loads. The hazard of living in a pub.
I was 14 and a bloke, late 30's, asked me if he could take me swimming. I said yes, if he got my dads permission, I pointed at my dad standing at the bar. He said "that's your dad?" I nodded and he downed his pint and left!!
