El Gringo (2012)
The Man: Agua, por favor.
Anna: Do you have any money?
The Man: What, you don't take American money?
Anna: I don't take fake money.
The Man: 200 dollars for a glass of water.
The Man: 500 dollars for a glass of water. That is my final offer.
Anna: [Pours him a small glass of water] You can't drink that. You're a gringo. You ever hear of Montezuma's revenge?
