- parking (bikes/cars/none if only pedestrians are there)
- some rest/change area for employees
These things cost quite a bit of money.
Now, as with most gig-economy "startups" (or should you call them moneybaths?), the "dark stores" require these things too, but at least with the locations I saw, they don't really do that. Essentially their fronts look like a branded homeless-camp. No thanks.
Also: can someone explain to me, how this concept will (like that of any other gig-economy company) be realized in any semi-equal society (aka no slavers state). Essentially you'd probably need 2/100 people working for that, nonstop. These people will basically do something which nowadays everyone but the richest people have heavily optimized already, just that it's not supposed to be optimized, because I don't think the idea is a soviet-style "hey, I bring you your allocated food, once a week".
The explicit promise is that whoever can afford this, can just call these services on a whim, meaning this is super-inefficient from a societal view (how do you optimize 10min delivery time?). Then, just letting the price decide and having all of services structured that way, you'll essentially get the slavers state, neolib. edition™. Because a lot of people working in these sectors will then be forced to choose the soviet-style solution outlined above (and you already see this!), just without being allowed a say in that matter, because that's how the system is supposed to be, no?
What a brave new world!
