Guessing by your examples that you are American. Maybe you are aware, or perhaps not, that in Europe many view your culture as the one that has taken this to its extreme. Some envy it, some don’t.

Where in Europe do you find large amounts of small stores? (and for real, not fake). Or is your point that Europe has a different supermarket chain per country? Malls have the same stores across countries ... but they differ, somewhat, if you move from one country to the next. And they're fake. Every company has 3-4 store brands these days so malls have 4-5 stores that look different, but aren't.

So ... what a difference that makes?

(I mean, I get that it does make a difference. Carrefour clearly takes some pride in their chocolate selection and aldi ... well it's an insult to any product to be sold at aldi. But culture in shopping in the EU? Where do you find that?)

Don't act as if the cities in Europe look any different. I don't know what a "subscribe n save is" but I can find a Western Union, gambling hall and vape shop on every street corner.
