Fortunately - unfortunately? - the one thing Jack does have plenty of is cash on hand. It's the one thing he has endless amounts of, and it doesn't care whose hand it's in, whose hand it goes to, what services or products it buys. It is always with him. He can always trust it.

Mickey snaps at him, raises his glass, and Jack responds by dropping twenty times what the drink is worth on the table between them, pulling it out of his front jacket pocket.

"How's this for business: take your cut in liquor or cash, I don't care," he says, and drops his empty glass down on the table next to it. If Mickey thinks the cash is that sweet, if it'll make him happy, Jack can do that. It's not doing much for him in this way. "Thank you for a kindness, Mickey, no matter what you want to call it but don't let it get in the way of business."
