No-one said that participants in a session ought to ignore their audience, generally, there is no 'audience' at a session, but other users of the pub, who have come to use the pub, not because the music is there.

I'll say once again, a session is for the benefit and enjoyment of the participants, who CHOOSE to go there, for their own pleasure. If someone goes to a session expecting to 'perform' to an audience, then as has been said before, they are way too full of their own self importance. I suspect you fall into this catagory Mr Campin!
