This feels a little short-sighted. Just this year, New York City implemented new minimum payment schedules for "self employed" app delivery drivers, which brings their minimum hourly payment to nearly $30/hr. I will strongly suspect that the big centres in california will do likewise, or potentially the state as whole.
Yeah, stopped using delivery for that reason. It got hilariously too expensive.
And it's no wonder. Restaurants delivering have very low overhead. A phone line and a delivery driver.
When you're on grubhub/doordash/etc, now somebody has to pay for a mountain of software engineers, marketing expenses, servers, customer service people, executive comp, etc. It inserted an expensive middleman where there was none.
alas, it's probably still a better option than each restaurant trying to build their own website/app. But not better than picking up food or calling the restaurant for delivery.
