The Soldiers in your unit don't see an HPSP doc who doesn't give a hoot and has been in for a year or two. They see a captain. That's an officer who is senior enough to know better. Try to live up to that if nothing else for their sake.
What they said above. I have my issues with my career choices and can rant with the best. But when you are on duty, no E-2 sees a doctor walking past them on base. They see an O-3/O-4/O-5/whatever.
Way back, I got a chewing out for something from a senior physician who was also my commander. At the end of a brief (but colorful) conversation, he pointed out that if any of my techs did or acted the way I did that day, they would immediately get papers. By disregarding the regs, I was inviting them to think it was ok, and then they would suffer the consequences (not me).
So, sure, there is a metric ton of crap I don't give a flying f!@# about. I do it, though. And if I'm going to do it, I try to do it the right way. It gets worse as you make rank. You meet standards because your folks expect you to exemplify the bar that they will then hold themselves to, whatever that ends up being.
When you have a serious case of IdGAF, the answer is: you fake it. You don't fake it for your own sake, but because a bunch of 18-20 yr olds will watch and in at least some way you end up as a role model (regardless of if you want to be or not).
Despite all of that; it is also perfectly acceptable to bitch,
privately, among
peers when someone gets obnoxious about the wrong socks or because you ran to the parking lot in scrubs. They may be right, but it is still really annoying when it happens.
