Unfortunately, that is the state of morality in the US. Some folks no longer are concerned with the other guy. I always say it's their world and we just live in it.
Some of us have been conditioned by politicians, clergy, entertainment and sports figures plus other high profile individuals that doing the wrong thing is right.
Not me, I plan, make reservations and cancel them within the required time if my plans change. Because of the bogus reservations I always have a backup RV resort or two to go to if I can't get reservation for my first choice of destination.
