Eeeep.

Just now, I was checking in some audio books for an older patron.  I asked her how she liked them.

Patron:  Well, this one was good, but the cover is all wrong.

Me:  Oh?

Patron:  Yes -- the woman on the cover is BLACK.  The woman in the story isn't black, she's COLORED.

Me:  ...   ...   ...   ...   Oh.

There aren't many people who are able to leave me speechless.  This lady does it consistantly, on an almost weekly basis.  I'm starting to think it's deliberate.
