I distinctly remember talks at the service meeting with scriptures that supposedly supported the field service reports. They scriptures were from Acts. "But when the officers got there they did not find them in the prison. So they returned and made report" Acts 12:17: "...."But he motioned to them with his hand to be silent and told them in detail how Jehovah brought him out of the prison, and he said: 'Report these things to James and the brother.'" Acts 15:27: "We are therefore dispatching Judas and Silas, that they also may report the same things by word." There may have been other scriptures.
I was a loyal dub, but I remember commenting to one of the sisters that I don't see how those scriptures support turning in a field service report.
