Kingdom Hall has "Book Study." overseers.
1. Book Study overseers have a percentage of publishers under their supervision, whether the Overseer wan't it or not.
2. The Public Speaker is offered a meal after the meeting, which is assigned by a different book study group each week. Since most of the JWs in their book study, rarely get together, this is a good time to talk to people away from the Kingdom Hall. You are able to praise the speaker (even if his talk was stale, not refreshing or loaded with his own agenda.) and his wife, while enjoying fellowship with those who accept your invitation to lunch, dinner. Often it is a Ministerial Servant who ends up taking the speaker, to take the burden off the elders. The policy of "Hospitality." looks good on theory but often is not implemented or is carried out begrudgingly. There is a elderette who hated this provision, use to drive her nutts having to take five or six people out to dinner. The speaker would bring a chain gang from his Hall, the elderette's husband would invite them all, and pick up the tab! $120 Poof! up in Smoke. Oh how she was mad!
