Into a dead end street

The cab swings down a darkened,dead-end street, it was December, so even though it was just 6:30, it was already dark. As the cab stops by a building, a skinny man looks in the back window at Melissa.

"Yeah, that's her. Stolen purse." Butch says and rolls his eyes.

Melissa catches this and responds "I'm serious, it WAS stolen and I—"

"I thought your car was stolen, which is it?" Butch asks her.

"Well, both actually, but really I have money at my—" She starts to answer him, when the door opens and the skinny man pokes his head inside.

Butch cuts her off. "That's alright, we have ways to attain payment." As he says this, the skinny man climbs into the back seat with Melissa and shuts the door as the cab drives off.

How do they "attain payment"?
