Boardwalk Empire, Season 3

Arnold Rothstein:
[discussing Rosetti's blockade of Nucky's liquor] It's bad for business?

Nucky Thompson:
Isn't it?

Arnold Rothstein:
And what would you know about it, conducting yours like a drunken shopkeeper?

Nucky Thompson:
Alright, Arnold. You're allowed to blow off steam.

Arnold Rothstein:
It's not alright. Do you think I entered into this arrangement because I value your companionship? You are a convenience, of geography and supply. You promised a quantity and a price. You have failed to deliver! And now, owing to your inability to manage your affairs in New Jersey - a state I have little interest in or affection for - you expect me to start a war? In New York? Where things actually matter?

Nucky' Thompson:
I expect you to understand that Gyp Rosetti is trouble for everyone. I lost an entire convoy...

Arnold Rothstein:
Because of your own cavalierness! Because you run off to Manhattan at a moment's notice to rut with some showgirl!

Nucky Thompson:
You'd be wise to leave Miss Kent out of this.

Arnold Rothstein:
Why? You can't. Do you even begin to understand how weak that makes you look?

Nucky Thompson:
That's a big noise from a man who is dead below the waist.

Arnold Rothstein:
I practice discretion.

Nucky Thompson:
You practice bullshit! Who the fuck are you, Arnold, aside from a little weasel with a good poker face?
