Absolutely. But many, most, times, they are leaving the LBS, or choosing an OP, because there has been something missing in their R with LBS. So they probably don't fear losing the LBS at the beginning. In those cases, gotta give them something to fear losing.
I don't disagree. I'm in favor of a short "Plan A" before going to bigger guns, esp. if you were legitimately an ass prior to the wayward spouse's infidelity.
