2023, it's all good.
I expected that answer and have to say that I agree, to a point. I think we are a bit more social in the fire service and a bit more informal, it's the nature of our job compared with a member of the CF. That's not to say that there isn't segregation, because there is, I just don't see it as clearly defined. We don't have tables for Chiefs, tables for Captains, tables for firefighters and tables for rookies - but you will see most officers sitting out of the banter, for the most part - just as an example.
IMO, it works. But it also works for those who are more personal with their crew. The crew they have understands that when the bell rings it's not playtime anymore and they are still able to function to their fullest, I see no harm in that. Can the military operate this way? No, not in my opinion, too big and too diverse. Plus the system they have inplace is tried, tested and true.
That's the end of my babble for now.
