What I have seen is that they ask if all agree, this is done by raising your hand. Never been asked anyone in disagreement? Presume due to the majority raising their hands. I never put my hand up for any resolution involving giving more to WTS.
Last resolution about the monthly contribution, i think i was the only person did not raise his hand and was confronted by one elder later about it. Just told him i don’t agree with the arrangement and changed the subject avoiding confrontation and checking if I believe in GB- too early to expose myself!
