About ten years back I had a courier contract to take 'devices' to Porton. I was not permitted to carry any other items simultaneously and had to be security vetted. I recall there were two gates to pass through, the first being the main entrance and the second was into the secure area of the establishment.
I had a super GPS gizmo that was used for getting a signature from the white coated recipient of each delivery. The sort of device that is now commonplace with courier/parcels deliveries.
So, there I am handing over the 'device' to a rather dishy lass in white coat and I ask her to sign on the gizmo. She asks me what it is and I explain the clever kit to her. "Ooh, that's spooky" she says. I look at my surroundings and laugh at the irony of her statement before exiting location PDQ.
No obvious side effects so far
