Re: Ain't no flies on you!
"I used to work in information security. If I had been asked to do a general review of the security of a location, a ploy was to arrive at reception, and then ask - with some urgency - to go to the toilet. If they were inside the building from reception, this often got you admitted into the building without signing in, without a visitor's badge, and without an escort. FAIL!!!"
I've seem someone use one of these (or a good copy) to gain access to buildings in a similar way.
