Responded to a chimney fire one time, at an old couple's place. They collared the chief before we went in, had a discussion with him. A little arm-waving, etc.
Turns out they were antique collectors- must have been a hundred thousand bucks worth of antiques inside. Primarily top-quality curved glass china hutches, completely lining the living room walls. We went into the attic, and put the fire out. Before we left, chief said the discussion was about whether to let us in- they wanted us to put the fire out from the roof. Chief had told them we had to go in the attic to make sure it wasn't on fire (and it was about to- embers were spilling out between the bricks). He told us that we would be prime suspects if they were burglarized- but they never left the place, had guns all over the house, and would shoot to kill.
