He can probably extend the runway a bit by swallowing his pride and looking into getting some free or cheap food from programs in the area, having a yard sale, etc. One food program found in a lot of areas requires a few bucks and 2 hours per month of volunteer work. I don't think they ask any info about your finances. (Maybe someone other than me can remember the name.)

If he happens to be in San Diego, I am familiar with some of the services here.

Best of luck.
