I thought that was happening to me too. I was getting the worst of the worst. Turns out, I was getting the difficult dictators because I could do them with less blanks. Some compliment, huh, nice paycut? Shouldn't I have been paid more for doing the crap? Needless to say I didn't stay long. I agree with the above poster. They don't care if you do them or not, they'll just find somebody who won't complain or will work for peanuts.
