The Watchtower rejected the offer as they could never submit to a lowly 'sister' instructing elders, circuit overseers, bethelites, district overseer, ministerial servants and brothers.
Problem solved. The Watchtower contacted the regulatory body and asked them to organize a training program at a substantial cost per head.
The regulatory body arranged for a qualified instructor and teacher to conduct the course. They looked at their list of licensed instructors in the area and sent the most qualified.
Imagine the surprise for all these brothers assembled at a local kingdom hall when the instructor and teacher that was sent was the actual sister, who they had to pay $500 fees for plus $25 per head instruction.
Idiots with 1950's mentality. Best story ever
