You really think Doordash sets individual prices for each dish for the half million restaurants that it lists on its service? It is a simple platform. The restaurant sets up and manages its own menu, and Doordash takes a cut of the final sale.
Based on the fact that other platforms like GrubHub hijacked Google Places registrations for restaurants and also presented menus of non-customer restaurants in the platform, yes, I would not be surprised at all if that type of shenanigans were going on at DoorDash as well.
