From Once Upon a Time in Mexico
[after giving Belini $10,000 in cash in exchange for information
Just for my own edification, I offered you fifty. Why'd you say no?
I'm not a greedy man. Not looking to get rich quick. Besides, fifty thousand is a lot for what you wanted me to find out. Could just as well put a bullet in my head as cough it up, see? But ten? Ten thousand is civilized. Ten is something we both can live with.
Ten might still be too much.
You'd kill me over ten thousand dollars? You wouldn't dare. You wouldn't dare.
