Where I live now, it takes 15-20 minutes to drive to the grocery store, so it's only practical to shop once per week. Shopping is a big chore and a fight with traffic, not a nice walk. It means I need to dedicate more of my apartment to food storage and more of my time to meal planning. It's certainly not an efficiency gain for me personally. On the plus side, the large store does have 73 different flavors of potato chips.
For example, here there's Tesco. But there's huge tescos, tiny ones in towns, tiny ones outside of towns, subsidiary companies like onestop that exclusively are smaller shops (we tend to call them "corner shops" here).
If anything, a larger central logistics "engine" behind it should make it much easier to pop up a new shop somewhere as most of the issues are solved and there's experience in doing it.
It does however make things more boring.
