Very nice touch. That whole scene was very powerful. And realistic:

Prominent Nevadans of that period, who could trace their ancestry in the state back three or more generations, believed they were entitled to play by their own rules and dictate terms to "outsiders" like Michael. You saw another view of the same attitude in "Casino," when County Commissioner Webb confronts Ace Rothstein about getting his worthless brother in law reinstated in a juiced-in job. I believe Oli posted that Texans have the same attitude.
