What do you do when they threaten to leave? If you can't quite get to "let me help you pack" (that is expert-level DB) practice "OK" and leaving it at that. Then walk away.
May, you might think that. But if you saw the reaction when you actually say that, and mean it, your DBing confidence would soar! After they fall to the floor in shock, they will come to and never threaten to leave ever again.
It is called "calling their bluff".
