Security Check

You never know what you will find in the public restroom.  While conducting our closing security check I was told by our circulation department staff and the security guard that the floor was clear and we were ready to exit the building.  While we were lining up to leave the floor I heard some voices coming from the far corner of the library.  When the security guard went to investigate, he opened the women's restroom door and there on the floor were two men swilling a bottle of vodka.  They were so involved in conversation that they failed to hear the closing announcements.  They apologized and quickly left the building.  What they failed to explain was why they were in the women's restroom and not the men's.
