Order food from doordash. Wait for some time after you place the order. Then try to edit your address. Due to some technical error you can't edit the address (not sure if this is vital or not). Click cancel the order. It will give you an error message that the order could not be cancelled because it was already out for delivery. You will get your food delivered and amount spent including tip will be refunded into your account soon. Fact is the courier will still keep their low payout for the trip. So, its a win win for everyone. Scale this but not too much.
