I know from personal experience that some Dommes put hard walls between their personal and work lives. It can be and might have been really jarring for the client/sub if that was so in this case.

Imagine making a great personal connection with attendant built up trust and then suddenly once the session starts, it feels like you're under the thumb of a complete stranger.

This happens the other way too. After session she wants to have absolutely nothing to do with you, like GTFO, which precludes aftercare of any kind.
