There are all sorts of rules and rationalizations like this. There was a carpenter in the last congregation I attended who was reproved for working on a church parsonage. He had been approached by a member of the church board who also happened to be his banker about making a bid on window replacement. He didn't really want to get involved, but decided that he better because he didn't want to disrespect the banker. He turned in a bid but jacked the prices up so high he figured he didn't stand a chance of getting the job. Well, he did get the job (was Jehovah providing or testing this follower?) and fullfilled the contract. Of course people saw him working on the parsonage (small town) and questions were asked and the elders got involved and he got spanked. Several months later the same parsonage was struck by lightning and needed to be rewired. The local JWs were surprised to see that the electrician doing the work was an elder in the congregation. The electrician elder expained that it was ok for him to do the work as the work was being paid for by the church's insurance company while it was wrong for the carpenter to do work there as he was paid by the church directly. The Pharisee's would have been proud of this explanation.
