I've heard many stories like these over the years of people living from their cars doing app based services. The crazy thing is most homeless people even the ones living on the street could actually do it and help their situation. For one most homeless people have phones these days so that's covered. Majority of companies give us free bags except for Ubereats and Caviar. The apps show you the directions so even if you're not aware of the area you can follow the map. If they could manage to get a bank account then it's pretty much set to start earning some cash. And even better most do instant pay these days. Just have to keep the hygiene and appearance clean and you good to go.
