This is the reality of the astoundingly terrible business of food delivery. Take something with already razor thin margins, add multiple layers of middle men each with their own overhead and create the amazing situation where the product is incredibly expensive but most of the middle man take either low or no margins and the delivery person collects a rent but then loses that right away on vehicle maintenance and gas in many cases.
It's the biggest lose lose lose lose of all time. The only real winner is the government who collects tax on this net loss of a transaction.
This is also why direct delivery like a pizza shop or chinese place with its own delivery drivers works but the app delivery model doesn't.
