I have had the pleasure of dealing with those individuals as well. One time at an event on the day I arrived (Friday), I unpacked, set up my camp, got my gear/ammo ready, combat gear put together so it would be ready to go and then so I could enjoy Saturday during the day and night I sat down to grade papers. A reenactor from another unit came over later and was telling me I was not being period by grading papers with modern day items (I was at a desk in the dark corner with 2 lanterns on the table), etc. I just looked at him and asked him if he was my wife, no then I pulled out the paycheck part that says void due to direct deposit and asked him if he was any of the names on it, no. Told him unless you are my wife or the person who pays me to f#(@ off and to just worry about his own unt. I've never had a problem since then and will do it again if someone tries that with me.
