From Star Wars: Episode IV - A New Hope
So. You got your reward and you're just leaving, then?
That's right, yeah. Got some old debts I gotta pay off with this stuff. Even if I didn't, you don't think I'd be fool enough to stick around here, do you? Why don't you come with us? You're pretty good in a fight. We could use you.
Come on. Why don't you take a look around. You know what's about to happen, what they're up against. They could use a good pilot like you, you're turning your back on them.
What good is a reward if you ain't around to use it? Besides, attacking that battle station is not my idea of courage. It's more like, suicide.
