One rule our Hall had was that families with young children should only sit in the rear of the Hall. If a baby got fussy, the attendant was to go to the mother and ask her to bring the child in the library or "backroom".
Also, disfellowshipped persons were to sit in the back of the Hall and if they talked to another df'd one in front of the congregation members, they were threatened with not being allowed to get reinstated and having a lack of humility.
Did your elders make up certain rules in your Hall?
