As a Canadian Reservist for 36 years I found most Regular guys/gals treated me just fine when I demonstrated I could pull my weight. The ones who gave me grief were usually plugs who did not get a lot of respect from their peers.
For the occasional Reg Force Puke that insisted on being a real ars*hole twards Reservists, my favorite line was "Your job is my relaxation from the trials of making it in the real world !"
The Bottom line from my POV has always been simple: The Reserve Force is as good as the Regular Force wants it to be.
