I went to that show with a friend, and encountered that same woman. She definitely seemed like a push over, but I didn't have the same experience, because we simply informed her that we were unarmed. She asked me something like "seriously, no guns?" as we were walking by her, and I snapped at her "No, no guns, but we're looking to buy some". She seemed in my opinion judging by the tone of her voice at that point to think that we were probably armed, but that we knew the way things worked, so she'd satisfied her job, and needed to move on to the next people coming through the door.
My guess is that at least one in 3 people there carried concealed to the show, and quite a few, including us left concealing a new gun or 5.
It amazes me that these shows always have people running them who are uneducated people with little or no business being there, and they get backed with absurd rules. The sad thing is it's still a better environment than the majority of Michigan gun shops.
