I've got a simple formula in life for when people do things beneficial to me: I praise them for it and encourage them to keep it going. If someone does things antagonistic to my interests, and then corrects course in reaction to objection, they can be sure they're going to be rewarded. This has worked for me.

If your belief is that some other tactic works, then I can see why you'd do that. For my part, carrot + stick has always worked better than stick + more stick.
