Where do you live? Do your firefighters just sit around taking no calls all day? Where I live (top 5 city in the US, with some of the most restrictive fire building codes) the average firehouse gets 80+ calls a day.
The hospitals, I guess? I'm making inferences from the judgement-making of...whoever, not second-guessing them.
If anything, I'm giving complete faith to the system here. My assumption is if they can send out a full fire-truck to respond to a call where clearly an ambulance would be sufficient, they're not doing it despite there also being a fire that needs response.
