Hey DB, I want to know what spurred the query, the scenario?

If I was solo and solitude was the gig, I would push on. If it was a lake that I wanted to fish I would stay... If I was in good spirits and the struck me as good souls or had kiddies I would leave the "good site" to them; maybe even make a chocolate cake for them or give a fish. If they were "_________" I would  enjoy the breezy point and proceed to sprawl, and let them talk crap and give me the eye ball and smile back. If the weather was crap or they were in a pickle I'd share, with an open invitation, and cook up a storm; leave the next morning even if it was a lake that I wanted to fish.

The "manners" thing is an interesting idea; a way. I always thought that it was a drag to have to stop so dang early to snag that site that has been on the list for many years; but that is the way of policy and use. PMA's here I come.
