Talk to Rebecca at her casino in The Den and ask for work. She tells you that Fred owes her an old debt to the amount of $200. He can be found on the west side of the Den, either in the casino or near Flick's. He looks like a junkie so you'll have to search until you find the right person. The one way to differentiate between him and the junkies is through use of the message box. It calls him a citizen of the den, rather than the generic message for junkies. Once you do find him, Fred can be shook down in a variety of ways:
Ask for all the money
Ask for the money, but allow him to keep a little
Tell him you'll pay his debt yourself
Whatever option you choose, head back to Rebecca and give her the cash. She'll split it with you as your reward.
If you allow Fred to keep some of the cash, come back and see him 6 months later. He'll have struck it rich at the casino, and will give you items for helping him: $2000, a plasma grenade, 200 small energy cells and 250 microfusion cells. If you turn down his offer, you'll get a measly +3 Karma (the reward seems to be level dependent - $1000 and a Buffout was awarded at Level 9).
