In The Las Vegas Story, the interiors of the Flamingo wouldn't be recognizable to anyone used to today's casinos. It looks more like a country club into which someone put a few gambling tables and some clunky old slots. Well-mannered people are dressed to the nines. Everybody knows the score and nobody cares. I've been here before.
Customers bring their own.
That's certainly true in this movie. They've come to this small, sort of seedy, and sort of gingerbread-house place, a city that doesn't look like the stridently surreal Vegas of today. But they've come for the same reason people still come, because it's a place where anything can happen. Everybody needs that feeling. But when people lose the feeling that anything can happen, they start to dry up inside.
