I have seen many over the years. A new co comes to town, and during, after or just before his next visit, often little pointless things change, sometimes big ones! And most of the time, there is no to very little of anything in the wt or bible to justify it.
The one that popped to mind while reading another post is this one!
Back when everyone still had magazine slots, the new co, had issues with them, because, some peons didn't pick up their stuff on time, and he felt it looked bad. That changed before the second meeting. After his last visit, the individual slots were all back, before the next meeting!
There are untold numbers of these things, and they rang from just funny, to totally assanin!
