I agree but I installed the “shopper” app which is the driver side for instacart while I was between jobs earlier this year. The way it worked is you get an alert so you open the app if someone placed an order. You then see where the order is, how much you will make and can accept it if you want. If doordash works similarly what it sounds like to me is you open the app, and see $x dollars and where it is at and decide if it is worth it to them. If they decide it isn’t, the restaurant is still making that food and waiting on another driver to accept the pickup. So if you open the app and see 3 orders, the ones that pay more and are closest to you is likely what you will choose. So if someone had a McDonald’s order and a BK order and one is paying a lot more) they are going to have a much better time. That is all based off the theory that it works like the instacart setup.
