I recall giving a Public Talk at a hall in Texarkana. THe hall had been built in the 1980s and sat about 225 or or more. Once tha hall was built, the cong was split into two congs. But neither cong grew. So there were two congs, one with about 70 pubs and one with about 80. I gave a talk to the smaller cong in 1996. The meeting attendance was abyssmal (sp?). ANhow...we had 55 in attendance for my talk. So less than 25% of the seats were occuppied. It was very discouraging.
SInce then that hall has been remodeled. THe old corner platform was moved to being along one wall and the semi circle seating arrangement was replaces with straight rows. Seating was reduced to about 150. The whole back of the auditorium is now just an open space. The spin put on this is that it gives more room for fellowship...
