Generally field service on Saturdays publishers met with their book studies. When the CO came everyone met at the Hall. Then after the meeting for service he told everyone to find their book study conductors and be assigned to a group. The point of everyone meeting at the Kingdom hall is to have a bigger group to work with and not work with the same ones we always did. The COs just got lazy and didn't want to do the work of making car groups for a whole congregation.
I didn't meet with the book study conductor and just left. People saw me there so I could say I was out in service. Afterall, that is all that matters.
