We have an old hardware/general store in my town. It has creaky, old wooden floors. Some of the stock must have been there since the 40’s. Owned by one family. You can bring in a screw and tell them you need one just like it and they reach in these old wooden drawers and produce one. They charge you 2 cents.
My friend who owned one inherited it from his dad and build it up such that it was a great local asset for keeping the community glued together and always moving toward a state of good repair).
My friend (saw him this afternoon with his wife) and his dad were both brilliant at meeting the hardware needs of this community. They had a vast knowledge which they made available to the community.
