You seem to be missing the point.
In Tennessee the firefighters did not put out the fire because the fee was not paid in advance. As I posted in a thread discussing that situation, I think the whole thing sucks, and if I had been a firefighter there I would have ignored the orders not to put out the fire. Nonetheless, the city is justified in not using their resources to put out fires if they choose to do that.
In the OP I posted the firefighters refused to put out fires that were already covered. The National Guard even had to show up to defend the firefighters who refused to obey the union and tried to put out fires, because the union condoned violence in order to extort more money from the city. You are correct that there is no comparison, yet the reason they do not compare has absolutely nothing to do with the point you are trying to make.
The real difference between them is that you seem to think that firefighting resources are free. Either that, or you think that a tax base is some type of bottomless pit, so that anyone who needs a service is justified in demanding it.
There ain't no such thing as a free lunch.
Except when a con wants one, that is. Some of the ski areas in Vermont now send a bill for services if that person has skiied off a clearly marked trail and needs to be rescued. You wouldn't believe the outcry from all the fat cats living in their starter castles up on Killington Mountain the first time some idiot got a bill from the Ski Patrol for $500 after they had spent an afternoon getting him unpried from a big pine tree.
As a side note, Killington residents, 99% Republican flatlanders, attempted a few years ago to secede from the State of Vermont and restructure its boundaries so it could move to New Hampshire where there's no income tax.
