Librarians who do school visits love to take a healthy supply of applications with them in the hopes of convincing new people to apply for a library card. So, i would make the suggestion that the librarian who is so chummy with the clerk "homey" to use the copies of applications which the clerk took initiative to run on used, otherwise recyclable, paper.
Now patrons can flip the page over and wonder what kind of legalese they are agreeing to by signing their application. This after having indicating some FYI jibber-jabber over how copies from the copy machine are logged by a counter in the machines mechanism; so the copier service continues to charge the library for paper the log counter shows as a single sheet per copy.
