Perhaps, therefore, it is odd that if there is any one phrase that is guaranteed to set me off it's when someone says to me, 'OK, fine. You're the boss!' What irks me is that in 90% of such instances what that person is really saying is, 'OK, then, I don't agree with you, but I'll roll over and do it because you're telling me to.
