If the restaurant has a relationship with the food delivery company, it gets charged a fee. These fees can be so high—15 to 30 percent in many cases—that the restaurant has no hope of making a profit from the order. “A restaurant's motivation to partner with a Delivery Provider is almost never to make a profit on orders received from the Delivery Provider,” the complaint says. “Rather, a restaurant’s usual goal is to capture new customers that may later place orders with the restaurant outside of the Delivery Providers’ expensive platforms.”

But Google didn't ask: they just added a "Order online" button. They decided which delivery provider will be in charge of the delivery and they didn't ask the restaurant.
