I don't know how DoorDash could make In-N-Out food worse. Seriously their food is not good. I see the trademark angle but the quality? Please they should start with making something worth while.
The fries at In-N-Out is an interesting paradox. Without sauce they taste almost like nothing; the blandest fast food fries I've ever eaten. With sauce? It's okay. A bit too soggy for my liking but okay.
Their fries are made fresh on site, but they do tend to need salt.
That's fine; I mostly meant out of the fast food places you're supposed to go to in CA I preferred them. As far as INO's fries are concerned I have yet to find a fast food fry that I thought was worse than INO's :)
I've used DoorDash before but not for In-N-Out...I wonder how many Stanfordians have done so, given that DoorDash is a product of Stanford graduates and of the incredibly annoying fact that In-N-Out is in the 2 nearby localities (Redwood City and Mountain View), but not Palo Alto or Menlo Park...Anyone who has been around the area know why In-N-Out hasn't managed to get a place near Stanford? This is the first California city I've lived in without its own In-N-Out. I would definitely use DoorDash for In-N-Out delivery.
On the topic I think the quality of food delivered is going to hurt the delivery businesses. Fries are the perfect example where you cannot stick them in a bag and delivery them 30 minutes later and have anything but a soggy mess.
I agree with others that these businesses are not going to scale but may survive in very small places where higher end food can be delivered and the fee is a smaller percentage of the total food bill. Delivering cheap fast food isn't a good business model.
