Hmm. Clerk, is a bit hard to say. Different camps and sirs will treat clerks very differently, so I'm not sure. SAFTI MI is basically OCS.
Anyway, one word of advice is try to be peace.
Don't suck up to anyone, don't offend anyone. Just be helpful and do your job as you are supposed to do it. Remain as a neutral party to everyone and everyone will generally like you, or at least won't trouble you.
Yet again, its hard to say. I got colleagues who suck up to my sirs and now they think they can walk all over us
