*growls* That brings up a memory from a job I held for five years; the office manager left and I had to do her job and mine, so I just applied for the position when they opened it up - more money and I was already doing it.
Couple months later, after continuously telling me they hadn't decided yet, suddenly we have a new office manager. It's the niece of one of the owners, fresh out of college and clueless.
I was supposed to train her. After two weeks she still didn't know the first thing about what she was supposed to do and I was fed up. So I quit. I wound up with a much better job which led to the one I have now that I love to pieces.
I still get irked when I think about it, even though the company went belly up a year later and I had the last laugh. Hang it there and remember that karma has a way of evening things up.
