Oh I witnessed one in a congo in Texas. We were voting on funds for new Kingdom Hall. There was a call for a 2nd. and all hell broke lose. The elder in the audience said it was being handled all wrong and the elder on the platform torted something back. they did this back and forth. I was like........woohoo........whats going on here. as it turned out the vote was taken back and we never got a new hall.
another occasion a school overseer was giving counsel to a young one. He was cruel. A brother from the audience said he was mean.......in front of all in the school and walked out of the hall.
