Local store here had a young woman who did not know anything about handguns, and just "wanted one", and didn't seem interested as the salesman tried to draw her out about her needs, any preferences, or questions she had.
She just kept asking to see different guns at random, and would use her fingers like calipers to size the longest distance from the top of the front sight blade to the bottom of the muzzle. Then they realized that what first appeard to be her putting her hand to her mouth in thought after each gun, she was actually transfering the measurment of her fingers from the gun's muzzle to see how it fit between her teeth in her open mouth.
Previous experiences had taught them it was not enough for the police to do anything, so all they could do was politely ask her to leave.
