I mean, it's not that bad. Delivery is an important part of many restaurants (pizza, jimmy johns (sandwiches), chinese in many cities). The issue in my mind is those restaurants with hugh delivery volume can do multiple deliveries in a single run, and can time the completion of the food to the return of the driver, so the food doesn't spend a lot of time sitting at the restaurant, and neither does the driver.

It's very hard to do that when you're aggregating restaurants and drivers.
