Not Worth a Hill of Corn and Beans

 is a unmarked quest in Fallout: New Vegas.

Walkthrough
This quest is given by the cook Cpl. William Farber on the Concourse at Camp McCarran. He asks you to help fix the food processor. You can either jury rig the fix (with a repair of 80) 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

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.

Bugs

 * The list he gives you says 1 (one) pot, but you need 2 (two) pots to actually fix it. Upon completion it will remove only one pot but you must have two in order to start repair. This bug was fixed with Fallout: New Vegas patch 1.2.0.31x, you only need one pot in inventory.
