Q: Given scene/plot descriptions from movies or TV shows, and given a specific question about the scene, summarize the question into a title
In one of the more famous Pulp Fiction scenes, Jules and Vincent are eating at a diner when Ringo and Honey Bunny decide to rob it. Their attempt doesn't go well. At one point, Jules tells Ringo to open up his wallet and take out $1,500. http://www.youtube.com/watch?v=3PeyiU3uWJ8&t=1m22s Now, I ain't giving it to him, Vincent. I'm buying something for my money. Wanna know what I'm buying, Ringo? "What?" "Your life. I'm giving you that money so I don't have to kill yo' ass." What does giving Ringo $1,500 have to do with not killing him?
A:
Why did Jules have to give Ringo $1,500?
