How is this different than doordash coming to pick up food from a restaurant and delivering to me? I think it's very similar, they charge an extra fee, restaurants might not sign up for this and it's not the restaurant employees handing me the food.
Of course, with that said, there was some service a few years ago (maybe it's Doordash?) that was generating landing pages and buying domains pretending they were the restaurant. But that's also very shady.
From what I head, the various delivery services have been setting up websites that pretend to be the actual restaurant's site, but list their own phone number. So they're committing fraud, too.
