When I find the “perfect” book in a used bookstore I say “Mine!” and hug it to my chest while doing a happy dance in my head (or sometimes not just in my head if it is from a series/author I am collecting). After I find that one, I usually don’t leave until I have a bag full of new friends.
I personally classify people who shelve books wrong as belonging in the circle of hell with people who talk in the theatre - if you don’t know where the book goes then leave it at the counter. I’ve done inventory - it is super annoying to know you have stock but can’t find it where it should be.
