Our Office Administrator is a single female and admitted today that she was using the installation of a security lock at the front door as a potential culling tool for prospective partners. That of course would be culling as "choosing" rather than as "killing". When the security lock was installed, so was a door bell - signed PLEASE RING. The doors had already been labeled as PUSH or PULL, depending on what side of the door you approached from. Anyone who stands outside and tries to PUSH the door labelled PULL without ringing the bell automatically gets excluded from the dating pool. Alas, there is no camera linked in to the video feed because there are some attempted entrances which are worthy of a "funniest videos" program. Hours of entertainment.
