When you're having a conversation through an industrialized medium, you may or may not like the fact that your conversation is preserved, but it isn't a surprise if it is, because you have the sense of it taking place through just such a medium (even if it's something you've never articulated).

If you're talking to a checker (or anyone) face-to-face, there's an absence of any explicit industrial medium. You're going to have the sense that whatever industrialized processes are in place, the face-to-face conversation is out-of-band. Of course it's going to be a surprise when it's not, short of explicitly notifying people otherwise.
