Firefighting in a large city versus a small town I assume are different, but the firefighters I know would never describe themselves as bored. They get paid to spend the majority of their time hanging out with friends, barbecuing, working on their cars, enjoying life, etc for the occasional hugely important and often terrifying life saving firefighting work.

They deploy more often than when I was a kid for EMT type work in place of or as first responder for ambulances. But, none of them would ever describe their day to day as boring.
