You could look into being a driver for Cisco: they supply a huge number of restaurants. Might give you connections that you could parlay into working for a different food distributor as either a driver or salesman. I also knew a guy who power washed businesses, like the exteriors. Just showed up and washed the outside walls. I had no idea this was a thing. I think he had to do it overnight though, so might be potentially dangerous in certain areas.
