I don't know if high society is different in other cities, but in Hollywood important people can't stand to be invited someplace that isn't full of other important people. They don't mind a few unfamous people being present because they make good listeners. But if a star or studio chief or any other great movie personages find themselves sitting among a lot of nobodies, they get frightened - as if somebody was trying to demote them.
