That's actually how a lot of businesses in rural parts of Alaska work, even places that don't require a boat or plane to access. My dad lives right off the highway in a small town in Alaska, and the closest thing to a grocery store is an old airplane hanger that one of the locals runs a general store out of. The owner makes weekly trips to Costco, which is ~4 hours away, and buys as much as they can fit into a big U-…
Rural Croatia too, except it’s a truck that comes to all of the villages 3x/week with staple items. Plays ridiculously stereotypical Croatian music through a loudspeaker to announce his arrival. And then a meat truck once a week and a fish truck more irregularly. Took requests as well. I think of it like villages having Amazon Prime starting in the late 90s.
I would have thought Croatia to be small enough to not need such a system; i.e. supermarkets not further than half an hour drive away.
Or is it just a matter of convenience?
