We have a couple of independent ones of those where I am.
One has been going for decades. It used to be in the next village along from where I grew up. It moved a few years ago, but it's still very much the 'neighbourhood hardware store'.
The other one started out in the city centre but was a bit of a pop up and I think the city centre lease was probably too expensive. It moved out to a very MN suburb (opposite Waitrose and next to an artisan bakery, no less).
But both are very much the sorts of places where you can go in and buy 4 screws if that's what you wanted.
