To my knowledge there is no rule saying one can not call an emergency group conscious right after any meeting, so keep that in mind as I continue on babbling! LOL
First thing I would suggest is to pray and meditate on this.
Second thing would be to speak with your sponsor and draw upon his ES&H.
If I was your sponsor and you came to me after prayer & meditation, I would suggest calling a group conscious right after any meeting that this guy shows his arse and see how others feel about it and what actions they would like to take.
Pray for him & for guidance.
