Not Worth a Hill of Corn and Beans

Not Worth a Hill of Corn and Beans is an unmarked quest in Fallout: New Vegas.

Detailed walkthrough
This quest is given by the Cpl. William Farber on the Concourse at Camp McCarran. He asks you to help fix the food processor, and gives you a list of the parts necessary to fix it. You can either jury rig the fix (repair skill of 80 required) or find these items:
 * 2 pilot lights
 * 2 pressure cookers
 * 2 conductors
 * 2 firehose nozzles
 * 4 fission batteries
 * 2 steam gauge assemblies
 * 2 sensor modules
 * 5 scrap metal
 * 1 pot

In addition to the aforementioned list, you will also receive a Meat vendor list.

Speak with Fitz, Ruby Nash, or Blake to make a deal. Angela Williams at the OSI office recommends talking to Contreras; this may cost the player some caps.

The reward given is a discount on his (limited) food merchandise. Note that this quest does not count towards quest completion, and you do not receive any experience for completing it.

In other words, it's "not worth a hill of corn and beans".
