On the subject of Nevadans and their hostility towards 'outsiders', there is a piece of dialogue from Casino that perfectly encapsulates it. The Gaming Commission representative (Webb) goes to see Ace Rothstein, who has just fired a local Nevadan for incompetence.

WEBB
(Chuckling)
You have got me there. Old Don is as
useless as tits on a boar.
(Chuckles.)
But, he is my brother-in-law, and I
would look on it as a personal favor
if you'd think some more on hirin'
him back.

ACE
I can't do that. And I appreciate
the fact that he's your brother-in-
law, and I do want to help you and I
like to do favors, and I know who
you are, but I cannot do that.

WEBB
Well, could there be any position...
further down the trough?

ACE
(Pause)
I'm sorry, I can't do anything. He's
too incompetent. And the bottom line
is, he cannot be trusted.

The telephone rings. ACE picks it up.

ACE
(Into telephone)
Okay, thanks.
(To WEBB.)
Um... you know, that's it. I'm sorry.

WEBB
Mr Rothstein. Your people never will
understand the way it works out here.
You're all just our guests. But you
act like you're at home. Let me tell
you somethin', partner... you ain't
home. But that's where we're gonna
send you if it harelips the Governor.
(Pause.)
Thank you for your time.
