Within a few moments, I was met by another uniformed agent, who directed me to a glass-enclosed cubicle located between the screening belts for the B gates at BWI. On my way to the cubicle, I had observed a sign indicating that travelers have the right to decline the imaging machine and “request” a pat-down instead. It struck me as odd that in order to really see and absorb the information posted on the sign, you would have already passed by or through the imaging machine.
