I used to own a service store years ago. I had the elders wanting to DF me so bad. They would follow me around and found me working at a church. That is a no no. When I had worked in the Elders store that I separated from and started my own in the same town, they would tell people who came in looking for work to be done on their church that only JWs were gods people and their church is run by Satan. That wold go over like a lead balloon.
After starting my store I would do all the churches I could. This would lead to a great bit of work from the parishioners. But the elders came knocking. My GF who was an elder knew they were trying to railroad me and said if the checks are from a private individual they can not do anything, only if the checks are from the church itself. So I would tell the story to the church and the issue and they would no problem pay me with a private check.
So I was not working for the church but for an individual that had me work at a church. In the eyes of the cult its like a roofing company you work for that happens to do some work now and then on churches, you can work on it if its not the only thing the roofing company does is work for that church. Talks about some ticked off elders.
