It can be a powerfull tool, and not backfire, if you follow 2 steps with it; make sure he is not a husband or boyfriend and they are just having a bad day; listen to how they address each other, watch her eyes, if she looks at you with a bit of a pleading look, you can move in.
When you say your line and take her away from the AFC, you must DHV right away; she will be thinking in the back of her mind "im glad this guy took me away from that jerk, but will he be worse?" I give her a sypathetic smile and say "are you okay? My last girlfriend was a model and I had to do that all the time for her". This shows DHV by making her think models go out with you. I then go cocky funny with something like "I'm not going to save you again, though; you have to stop being such a cute little flirt!" This usually breaks the ice, and they give me
kino, like a playfull punch on the arm. Make sure you give her a little personal space during this; the AFC usually was crowding in on her and she will be repelled by the same behavoir from you for a minute or two. Go to your most comfortable routine, and when you start getting IOI's, gently take her by the hand or elbow and isolate, she will be attracted to your alpha behaviour that she didn't get from the AFC.
I have had good luck with this, if you do it right everything in the female mind clicks right for seduction.
