I would try to remember that this is an institutional meeting with a very specific purpose, to carry the AA message to the alcoholic who still suffers, to give them hope that they can have a better life.
It is not a regular meeting and could be shut down if the inmates or members of staff feel visiting AAs behave or share inappropriately. I have seen it happen.
A guiding thought might be the Torono Declaration "When anyone, anywhere reaches out for help, I want the hand of AA always to be there, and for that I am responsible."
It is a great opportunity to show how we have lost interest in selfish things, and gained interest in our fellows.
