Corrupt bastard boss

So I work 4-5 days a week on the road. My boss told me at least 3 times to pad my expense report, pick up receipts off the ground, fabricate receipts, a.k.a. steal from the client like he does, because "business travel is a such a burden and I could use the extra money to get an airport business lounge membership". The guy makes at least 6 figures and I do allright, why the fuck risk my career for a couple hundred bucks. I finally told him that if I really wanted the f*cking business lounge membership I'd get it myself, no thanks on the nickel and dime microembezzelment. (Well that's what I was thinking, I said it a little nicer without calling him out as a thief).

I'm ready to get out of there for other reasons too, but that was the last straw and I really lost all respect for my boss after that. And I can't work for someone for whom I have no respect. Don't insult my integrity motherfucker.

I may need the guy as a reference so do I bite my tounge and move on quietly? He's the one I'll be handing my resignation to, and I'd love to tell him the real reason I don't want to work for him anymore. Ahhh, the joys of work.
