New ATF vs Old ATF

Me and my old ATF had a great run, but eventually you're going to get tired of it and want to move on, and that's what happened to me. I would still talk to her and tip her every now and then, but I don't get dances from her anymore. My new ATF works at the same club. The main problem is that the two of them are the best of friends. Whenever my new ATF would lead me to the lapdance room, I would make sure my old ATF was nowhere in sight so that she wouldn't see me get lapdances from another person (especially not her best friend). One time during a lapdance, there was some DFK between me and my new ATF, my old ATF was leading a customer to the lapdance room, so she saw what was going on. As I was leaving the lapdance room, I glanced at my old ATF and she gave me an icy stare. I didn't see her the rest of the night (it should be noted that me and my old ATF had heavy DFK sessions in the past).

I'm wondering has your new ATF ever been best friends with your old ATF working at the same club? How did that work out? How were the interactions between you and your old ATF? How did this affect you and your new ATF?
