Uber Eats or Doordash: Can a restaurant cancel a driver (or request a new one) if they have had issues with the driver before?

The restaurants can cancel orders for pretty much any reason at all. It stinks they'd lose that business, but maybe they can do that if they have serious concerns about the driver or it's some fraudulent order placed by the driver or something.

The mechanism is there on Uber or Doordash to deactivate bad drivers with bad reputation. More issues they have on their record, it's more likely they will be deactivated. The restaurants have to trust the system and continue to server the food. That's their part of the bargain, and they need to keep it up. 

It does stink that when something goes wrong with the order and a refund is issued to the customer, the restaurants do lose out on the food they served.  For cheap foods like pasta and sandwiches, it may not be a big deal, but for higher cost items like steaks and seafood, they can really lose out.  This is something each establishment has to assess and decide.

I don't know the answer but I think the restaurants just receive the order, prepare the food, and leave it there for the driver to take, right? I am not sure in which step in the process, they can review the driver and cancel or modify.  So I am suspecting the answer is no.
