When automation is not complete, humans can hang around for a bit longer, but there will still be fewer of them than before. If all restaurants did was automate order-taking and paying (some are painfully close to this already with on-table tablets that it's actually annoying they haven't already), they just need a human who doesn't speak to the customers to make the food, deliver the requests, and clean up. Maybe a traditional waitress or two if they wish to serve the occasional customer who can't or won't use the new technology. The needed staff size to run a restaurant is lower in any case... I'm also curious what truck drivers' value is besides the driving. The main thing I see is doubling as role of security guard -- a minor deterrent to anyone wanting to rob the contents of the truck. So there may be some value for them as ride-along security once automated driving is here, but perhaps only if the problem of people blocking the road to trigger the truck's automated driver to stop and be robbed is serious enough or happens roughly equally along all routes at all times (unlikely).
