I was in one congregation in which the elders decided to "lift the tone" of things by insisting that men wear jackets at all times while engaging in field service. This in a location in which summertime temperatures frequently exceed 30 degrees Celsius; and in which the community in general would regard you as being barking mad if you did not remove your coat!
In another circuit during the late 1980s, all those desiring to get "get appointed" were required to not just make the "national average", but to exceed it. Would-be Ministerial Servants had to report at least 12 hours a month, while servants who hoped appointment as Elder had to report at least 15 hours a month. All congregations in that circuit were spilling over with publishers, and we were covering the territory in less than a month. In fact, during the Circuit Overseer's visit, coverage was more like once a week. People were (not surprisingly) heartily sick of us always being at their doors. By the time I left, the list of "Do Not Calls" almost exceeded the number of homes it was okay to call at! Also, the official stance of the WTS that you "worked a territory to life, NOT to death" proved to be quite untrue. Nontheless, the iron-clad rule remained, "Thou shalt report 12 hours a month". Not written anywhere in the Bible, though. (Certainly nowhere that I could see, anyway!)
