I think this might be a balls and strikes argument, if that is the case, leave it on. The only reason you should take of the mask is if you have something special to discuss or if you expect that conversation to be long. I have left my mask on when a player wants to debate judgement calls, but if I know it is a serious discussion about a rule or something that will take time, I take it off. I think this is a personal thing, but leaving the mask on in this situation as it appears it was appropriate.
