Maybe you're right, but I can't help thinking that a lot of FAC holders and wannabe FAC holders don't really help themselves in these situations.
I think FEOs have quite a difficult job, really. But I've always found that through a combination of honesty and humour I've got exactly what I wanted within a reasonable timeframe. There's a fair bit of psychology involved I suppose: He's trying to assess you, but you also have to assess him in order to pitch yourself at the right level.
Let me tell you a tale:
A little while back, I posted this:
There was a lot more to the story than that obviously, but the bottom line is that I was acting outside the conditions of my FAC.
I told the story to my FEO at my recent renewal visit, and when my new FAC arrived in the post it had "humane dispatch" added as a condition for my .243
No questions asked.
These guys are human. Treat them as such, and a lot of your perceived problems dissappear!
