Not Worth a Hill of Corn and Beans

Not Worth a Hill of Corn and Beans is an unmarked quest

Detailed walkthrough
This quest is given by 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

The reward given is a discount on his (limited) food merchandise, and 80 XP if the Repair skill check is passed.

Behind the scenes
The phrase "hill of beans", meaning something that is not worth much, was popularized by actor Humphrey Bogart in the 1942 film Casablanca.

Bugs
Occasionally, it doesn't allow you to fix the processor even if you have all the parts, one more part is needed. You will need one extra pot in your inventory, only one pot will be removed when fixing the food processor.
