After going through USBC rules on Pre/Post Bowling. Two things I see missing with leagues is they do not have a committee for Pre/Post Bowling and, they do not follow the procedure. If you read through the rules a committee gets a request, and then grants the pre/post bowl to happen.
What I see with most leagues are members taking liberties with this rule. They have adopted this idea that they can show up any night of the week to pre/post bowl.
What a mess.
If they truly followed the rule it would make things for the league officers, the league, and especially the proprietor much easier. It amazes me today with all the ways we can communicate (phones, text messaging, emails, internet-facebook) that making a request to pre/post bowl is so hard for some to do.
