These days as soon as a green\lockbox drops, I hit my "Let's see who needs on that green\lockbox" macro. It's never a case of "Oh gosh, I wish I thought of rolling need on that..I'm so mad...Grrrrr! I must exact revenge on them" If it makes that person feel better to think that's why they got kicked, then they think that while they wait for their que to pop again.
Obviously, if the group agrees enough for a vote kick to pass, then more than just 1 or 2 people disagree with needing on greens. it has nothing to do with value of said green. Again, it's a douchbag test for many. Fail the test and they'll seek to remove you.
