Three sides, each with its own screens. Shops apply from the site and wait for approval, run a self-refreshing kitchen screen, and can flip a switch when they are drowning. Riders claim the jobs they want with the fee shown up front, and can hand one back until they have collected it. You approve both, set the rate, and batch the payouts. Commission is set per shop, because negotiating a lower rate with a big vendor is the normal thing to have to do. The cut is shown plainly on every payout — what came in, what the shop keeps, what you took. Hiding it is what makes vendors leave. A basket per shop. An order spanning two kitchens is two orders, which is the only version that survives contact with reality.
