On JW Broadcasting there is a video of a Missionary couple who were sent to a Navajo reservation. The sister says the thing she learned most at Bethel was "shovel the coal, don't question the captain". It's worth watching about 60 seconds from the 4 minute mark. It just shows what the GB think of themselves and the "stokers"!
