Why do folks have such different experiences with these things? Me and some friends I regularly hang out with regularly use door dash to get food for all of us. We're all web devs and fairly picky about website speed and no one has ever had any problem with the doordash app. Maybe some weird things with edge cases with restaurants that have combinations of sides/options that don't fit the doordash ui well, but not general slowness.

I would most definitely not want Doordash to die a quick death and I'm sad that you do! If not for their existence it would probably be too much trouble to do the research about restaurants in our area that are open, what their food is, how to order, then place the order via whatever novel phone or buggy online ordering system they've set up. We'd probably just end up ordering Domino's every week instead of what we do now which would be worse for everyone!
