So I'm standing in the local library, right? Right in the middle! About ten feet away from the librarian, and looking around in puzzlement because they just rearranged everything. Again.
Because our library isn't that strict about noise level, I just sang out my question instead of walking over and whispering--
"Hey! Where's the shelf for the adult videos?"
No! No! No! Not that, I meant, you know, the not-juvenile ones! The regular section! The DVDs!
FEATURE FILMS, was the term I was looking for.
