That was my Colt AR9mm on my table at Rochester, that SP10's friend picked, up and thereupon inserted the magazine. He did this after removing the " PLEASE DO NOT HANDLE WITHOUT PERMISSION" cardboard sign that was on top of it. There was no communication between the individual and myself, either verbal or by eye contact at any time. If he had talked to me, I would gladly have talked to him, answered questions, allowed him to insert the magazine, cut the "wire tie" securing the charging handle, work the action, open it up, whatever. The purpose of the tie wrap, in addition to being a show requirement as a safety factor, is to preclude the "tire kickers" from playing with the piece to impress their friends, their kids, others standing around, their wives and /or girfriends, ans especially the vendor, with their total familiarity and mastery of the "evil looking black rifle". (ARs seem to be especially worthy of "tire kicking" at shows.) Gun show etiquette usually requires some contact between the customer and the vendor prior to handling the item, especially if a sign requests this contact. I did not say a word or "bitch" when he removed the sign, or when he picked up the rifle. I did "bitch" when he picked up the magazine and inserted it into the receiver. If I appeared rude, I apologize, but I do not feel "the customer is always right". Just my opinion, I could be wrong.
By the way, the Colt is still available for FTF in western NY.
Good Day to all..
