Why I Don't Work in a Public Library

A public library director posted this message on a list-serv today. I'm grateful for public libraries and the librarians who serve there, but I'm also glad I'm not one of them.

To Those Who Have Done This Before; How do you handle access after detecting evidence of obnoxious/illegal/unsanitary/gross activities taking place within your public restrooms? I have been living in a Fool's Paradise, apparently. Sigh.
