Friend of mine ran our local hostelry a few years back. The only kids he let in were offspring of regulars he knew. Reason being he knew his regulars could be relied upon to keep their off spring in check and they wouldn’t mind a quiet word in their ear if the devils got out of hand.
When staying at the RAF Club, we always take the kids to the Running Orse, where most people seem happy to see them. They tend these days to sip a lemonade and are happy playing with an electronic device ( turned off of course) and are hopefully no bother to other members. If they ever get too excited we would take our drinks to our room.
