I'm no hero but I told an inspector "No" too. He asked to see my med, cert, Reg, and A/W. As he tried to look past me, I opened the door, reached inside, and handed him the Reg and A/W. Then HELD my medical and certificate so he could see it. He insisted that I hand it to him and I insisted that I would NOT. I ALWAYS carry copies of my cert/med so I offered him a photo copy (I always carry copies); he accepted. Told him he would need more than an I.D. to look in the plane.
He shifted from FFA talk to discussion about the weather. He left and went on to the next plane. No problem after that. Nice guy!!
