Forget the "delivery apps are expensive" argument. The really interesting part is how many people get paid when one person orders a burger.

The restaurant wants the customer. The customer wants the burger without leaving the couch. The driver wants to get paid for moving it. An advertiser wants that restaurant at the top of the screen.

And the delivery app? It sits in the middle of all of them. The food is the passenger. The transaction is the money machine.

The restaurant pays for access to customers. The customer pays for convenience. Advertisers pay for attention. Subscribers pay for cheaper access to the whole system.

One meal. Multiple revenue streams. Suddenly a $30 delivery order looks less like a ridiculous hamburger and more like a tiny financial ecosystem.

The burger just keeps collecting friends. A delivery fee joins the party. Then a service fee. Maybe a small-order fee. Then tax. Then the tip.

Suddenly your humble $15 burger is standing at checkout looking like it has a 401(k).

But here's the twist. The platform doesn't need to profit from just one charge. It can get paid by the restaurant, the customer, advertisers and subscribers. And sometimes, one transaction feeds them all.
