You know how sometimes customers are being stupid, and expect us to read their mind? They cannot figure out what they really want, and just don't have a clue? Or they order something wrong?
Well, often, I do realize exactly what they actually wanted, or what they stumbled over trying to order, but just give them the thing they manage to blurt out anyway, even though I know it's not what they want.
I don't know what that says about me, but I just don't care anymore.
