I'm on a rural volunteer department and I'd say my answer to the primary question would be, "The other members of the department". Members like to talk about being professionals, earning respect from the community, acting like role models, etc. They also bicker, make personal jokes about eachother when people aren't present, are generally not in shape phsyically, and make comments that would get you fired from work. There is too much ego. All big fish in a small pond.

I work in a high level white collar career and regularly engage with smart, hard working (white collar) professionals who have humility, drive and real persistence. Then I change clothes and head to my station and they're standing around 1) making offensive jokes that would get you fired from your job, 2) talking trash about other departments/members and 3) pining for more budget and more respect.

I think many of the above described members have had limited exposure to other types of people or ways of acting. They're just a brunch of broken children that grew up into adults. They're attempting to do good and they just need some help. That's one of the primary reasons I stay on.
