Ah this is how GrubHub, Uber eats, and other food delivery operated during the pandemic! They literally pretended like restaurants were on board, called in the order themselves, sent freelancers and then skimmed off the top.
It was so destructive to many restaurants that they were forced to change. Bad delivery drivers would tank their Google/Yelp reviews. Many created a custom window/spot for food delivery because they wouldn't know which were real call-ins vs food delivery.
Food delivery won because of cheating.
And Amazon is doing the same.
