Hunger/cook job sounds cool, pretty sure the server is sworn off of printers and stuff like that. I feel like shopkeep wouldn't stick well as there isn't always going to be someone to supply you with vital items sort of like gun dealers and BMD but more important.
Scavenging is in the works as wolf said and refineries would be an interesting addition especially if the oil rig was finally used, maybe some sort of multi-step system.
