While not "the last straw" for me, one that definitely made me chuckle (and encouraged my reluctancy to consider a JW "mate") was the food stand at the summer conventions. This was still when there was food and it was handled by the "ticket arrangement." My mom always signed us up to do the concessions, and I would usually be at the counter. However, while I was in high school, I got taken of the counter and relegated to "gopher." The reason? I could do the sums of the tickets faster than anyone else, particularly the elders and ministerial servants that flanked me. I could also do their totals while doing the totals for the people in my line. Instead of making good use of this skill, they got bent. (OK, this is bad, but i still consider myself "better" than those crackers.)
The effect on me was the realization (and generalization) that JW men were actually inferior to women, despite the public image of superiority. I left "bemused" by the shortsightedness of the JW philosophy of women in their organization. Their cult would probably be quadruple its size if it were an egalitarian organization.
Whatever, it's not my bag anymore.
