As Long As They Keep Allowing Patrons To Wander Unsupervised, Sure

I’m in the stacks looking for a book when a patron approaches me, very upset. 

Patron: “This is wrong!”

He points to a book that clearly doesn’t belong on that shelf. No librarian would have put it there, but sometimes people will take a book, decide they don’t want it after all, and put it back in the wrong place.

I take the book to return it to its rightful home.

Me: “You’re right. Sorry about that.”

Patron: “You know, I used to work in a library, and in my day, that wouldn’t have been allowed.”

Me: “Well, patrons browse on their own, and sometimes books get misplaced. We don’t always notice right away.”

Patron: “So, what are you planning to do about it?”

Me: “I’m… going to put it back where it belongs? Thanks for letting me know.”

Patron: *Sighs* “I guess you just can’t trust the library anymore.”
