I saw the video where it said sisters can used to assist the attendants and it seemed to be in the context of helping disabled females and children out of cars when they arrive at the convention. They have always used female "attendants" in "Mothers and Babies" dep (I was one) with a brother "overseeing" from outside (bizarre!) apparently because women can't be left alone to feed and change their own babies.
And yes, I knew many couples where the hubbie was indifferent to congregation privileges and appointments but was pushed forward by a very ambitious wife.
