I remember one of the few times I was stupid enough to go out with a girl from the hall (in my defense she was ridiculously hot) I pick her up (and yeah, somehow her folks didn't get the memo about no solo dates) and while she is putting on her coat her elder dad tells her right in front of me like I'm not even standing there that if I get out of hand for her to get on the phone pronto and he'll pick her up.
I'm thinking to myself, nimrod, if what I hear about your daughter is true (another one of the reasons I was stupid enough to take her out) I'll be the one calling you unless I have a padlock on my zipper. To her credit, the girl apologized profusely for her dad after we left, after which she went to work on the zipper.
As Michael Corelone said, That's a true story.
Edited to add: Didn't mean to horn in on your action Ritchie, just, stupid elder tricks have been around for a long time. Glad you gave it to the guy.
