Thanks much for your comments above, well thought out and organized. I have an excellent example of such a person, He and I volunteer at a steam powered sawmill, I and a helper run the (3) engines, this other volunteer has been posted to several other jobs, one of which was to help out with the operation of a steam donkey (road engine); this is one of those people who need to be "in charge" or whatever he is assigned to, in the situation that I witnessed, another volunteer was splitting a pile of firewood for fuel, by himself; over comes Mr. "in charge" and tells the man on the splitter to shut it down until he can be checked out in his knowledge of hand signals for the operation of a wood splitter --- which he complied with. Personally, I would have told him to F--- off, which I had done in a couple of other instances. Mr. "in charge" has been run off from another similar venue in our general area, I assume for the same reasons.
