Well, you tell your backer that you got jumped by those kids. If this is gang shit, they can't have their people getting jumped. So you tell those people what happened and will still probably have to work off the debt. You can't go unprotected. You'll have to keep cash stashed securely close to your body. Keep some petty cash in your wallet for the stick up man to think he's got your stash. Once you have the cash, you're going to need a pistol. These kids got cash off you once, they'll be back if your backers don't take care of it. Or, you know, stop selling drugs and whatnot.
