This putting-up-signs thing has happened in a way, and we know how this turns out. In some rural areas there are places where the fire brigade is not paid for through local taxes, homeowners have to contract individually with the fire services to come.
When a homeowner has a fire put but failed to pay the firemen the fire brigade does come out, makes sure that the inhabitants are safe, and then lets the house burn down and makes sure that is does not spread to the neighbors, who have paid for fire service.
Next thing that happens, everyone hates on the fire brigade because they did not put out the fire. People need to be prevented from shooting themselves in the feet.
Well if they did not pay for the fire brigade, what do they expect ?? It's like wanted the cake without paying the bill. I do not see anything shocking in your story. If I do not pay for a service, for an insurance, I am not supposed to get the benefit from it. It's perfectly natural.
This attitude doesn't conform to observed practice. Every time this happens people from that community come out, saying the firemen should have stepped up even though that party did not pay. There seems to be a feeling that we are our brother's keeper.
(There's also the other problem that when someone's house burns down, such a person will likely become a ward of the state, and that can't be allowed to happen. That's why in some countries it's mandatory to carry fire insurance.)
