Oh I see. I actually like that! I don't think I would ever use one of these services to eat at a strangers house. However, if I could go on and see a list of what people in my area are planning to make (oh boy my neighbour is planning to make a batch of brownies this weekend). Then I could opt in and pay for a certain amount before some deadline.

Then the person making the food sees that they need to make an extra x amount of brownies (but they were already planning to make them, but now can make some extra money!). Then when they are ready you get an alert and can go pick it up.

That would be pretty sweet! I'd use that.
