Food trucks are a “thing” even in areas without a minimum wage. Atlanta has tons of them, for example. And these are not at all your construction site roach coaches from days of yore. I’ve had wonderful lobster rolls, burgers, tacos, sushi, etc. from food trucks.
Our town has one evening a week from early Spring through late Fall where there is a food truck event at a city park. It is quite well attended.
This is all good news. There will be a lot of building that can be turned into homeless shelters that have kitchens to serve them.
