Sorry to not be clearer: when I talk about market making I meant for the restaurants to be put in touch with delivery people so they can negotiate that themselves, off app, rather than having Deliveroo involved in the process.
It’s not a very coherent idea other than the usual “crush the rent seekers! [Deliveroo]” I guess.
You forgot 'delivery'. Many people don't mind paying an extra $10+ to have someone else pick up their takeout meal.
