Ignoring the fact that ordering online or with an app asks you to tip before the service actually happens, I don't even know what exceptionally good delivery service would look like. I'm paying someone to drop food off next to my door within a certain time frame, there's no way they can do it any better and a million ways to do it worse. Tipping deliveries is nuts. Thankfully I recently moved out of the suburbs and now have dozens of restaurants in walking distance, so I never use Doordash or whatever any more anyway.
