Anton Chigurh: What's the most you ever lost on a coin toss.
Gas Station Proprietor: Sir?
Anton Chigurh: The most. You ever lost. On a coin toss.
Gas Station Proprietor: I don't know. I couldn't say.
[Chigurh flips a quarter from the change on the counter and covers it with his hand]
Anton Chigurh: Call it.
Gas Station Proprietor: Call it?
Anton Chigurh: Yes.
Gas Station Proprietor: For what?
Anton Chigurh: Just call it.
Gas Station Proprietor: Well, we need to know what we're calling it for here.
Anton Chigurh: You need to call it. I can't call it for you. It wouldn't be fair.
Gas Station Proprietor: I didn't put nothin' up.
Anton Chigurh: Yes, you did. You've been putting it up your whole life you just didn't know it. You know what date is on this coin?
Gas Station Proprietor: No.
Anton Chigurh: 1958. It's been traveling twenty-two years to get here. And now it's here. And it's either heads or tails. And you have to say. Call it.
Gas Station Proprietor: Look, I need to know what I stand to win.
Anton Chigurh: Everything.
Gas Station Proprietor: How's that?
Anton Chigurh: You stand to win everything. Call it.
Gas Station Proprietor: Alright. Heads then.
[Chigurh removes his hand, revealing the coin is indeed heads]
Anton Chigurh: Well done.
[the gas station proprietor nervously takes the quarter with the small pile of change he's apparently won while Chigurh starts out]
Anton Chigurh: Don't put it in your pocket, sir. Don't put it in your pocket. It's your lucky quarter.
Gas Station Proprietor: Where do you want me to put it?
Anton Chigurh: Anywhere not in your pocket. Where it'll get mixed in with the others and become just a coin. Which it is.
