I don't know why anybody is voting this comment down. This describes my local library to a "T". You wouldn't dare allow your children to use the restroom unescorted for fear of what they might encounter. Also, the furniture and carpets are infested with fleas. At least with a commercial establishment the owner has some control over the environment.
I like the idea that someone would downvote a comment based on the idea that "my library isn't like this, therefore these guys are trolling". Who knows. I've mostly seem wonderful libraries in the US, especially in Pittsburgh, but I'm sure plenty of places have their problems. There would always be a few bums asleep in the Carnegie (discretely, mind you).
Yup. The downtown library in my town is the same way; my wife refuses to go inside. I usually just have books transferred down to the library close to my house rather than deal with that branch.
