I hear vending machine ppl often have 1-3 very profitable locations and 10-40 locations that only barely make sense often only because they already are in the business.

I imagine hiring someone to fix or restock them makes a lot more sense if you have 100 machine rather than just one.

It really depends what the goal is. Profit with fiber or fiber with profit?

Here public transport is required to cover all routes. Postal service is the same. Fiber doesn't seem that different?
