As I have mentioned in previous posts (like this one), I volunteer at a library.
In general this entails just filing books on the shelves and also pulling ones that are requested by other libraries in the system. However, there is some patron interaction and also some unavoidable patron overhearing.
Like any institution open to the public, there are regular users of it and these get to be known for their attitudes and preferences.
Now, I would dearly love to talk about some of these characters to the library staff and also anonymized here, but I feel strongly that that is illegitimate. People who come on a public resource for use should feel that they are not required to exchange their dignity for the use of the place. Just the same, the desire is there. I don’t see a way out.
