I was checking in at a small Southern airport when the county sheriff stepped up the counter and heaved a softball-sized piece of steel onto the counter. He said: "She missed it again." I assumed it had to do with the screener.
Anyway I went through the screening process right after the sheriff had chewed out the security woman and she reset the sensitivity of the metal detector. I was stripped down to t-shirt and Bermuda shorts and no shoes or socks. She kept wanding me and telling me I had steel in my feet. What a fiasco.
