So a nearby pizzeria with its own delivery drivers that has a degree of operational competence can get that pizza in a car immediately, which means that the customers get better pizza, which means they order more pizza from that store.
Uber Eats and DoorDash don’t seem to manage to get pizzas into a car immediately.
I was a little annoyed at the time, but now that you've put it like that, it makes a lot of sense.
I went from hot pizza arriving in 15 minutes to cold pizza arriving in 40+ minutes, if at all. After a few times, I realized the delivery person was now a random doordasher that didn't know the neighborhood, and didn't even have the benefit of seeing my doordash instructions on how to find my townhouse since they were hired by the restaurant.
This is what I was thinking. I don’t live/work in CA, but restaurants in NY who self-deliver also have to consider the high cost of Insurance for delivery drivers compared to the availability of third-party delivery agents.
