I was involved in a Launch recently with 2 other Instructors. During one track (which one of them was teaching), they both suddenly turned to face the mirrors. The participants seemed confused. It completely threw me as suddenly we had 2 instructors facing one way and me facing the other way (I, of course, was facing the class). The participants in front of me were pulling confused and angry faces at what was going on and I was left shrugging my shoulders and pulling confused faces to them mid-track as if to say 'I have no idea what is going on!?!?"
It looked a total mess and they continued in this way, so I walked out. I left for the two remaining tracks they were teaching and then came back when it was my turn to teach a track and stayed until the end. No way am I going to compromise my LM training and the CORRECT way to teach by being a part of that! Fortunately I am professional enough to have done it in a way that looked like I was leaving for a reason and not throwing a tantrum.
There were also alot of other things that they did that are not relevant to this topic.
When I queried everything with them afterwards I was met with denial and indifference (one even said he had NOT faced the mirrors 
). I made the point clearly that you cannot CRC if you are facing AWAY from the participants (i.e. facing the mirrors). I therefore told them I would not be participating in any launches with those two again as a result.
It provoked a bit of a storm, but I do believe in standing up to so called 'instructors' that deviate from the program just because THEY feel like it.
I guess they still do this but I decided I can only raise my disapproval and if it gets ignored, then I just need to ensure I keep 'my own house' in order 
.
