If a brother is an experienced builder and another brother says something has to be done a certain way , that usually created nasty arguments - so yes I have seen this sort of thing before at builds
I have seen this quite a number of times. The worst trouble comes when the experience brother is 'just' a publisher and the other brother is an elder construction overseer. The whole JW thing is a hierarchy; and the senior person has the last say, not the most suitable. Eyeslice
