Damn, sorry to hear about your bad session with Lina. I've had 2 really great sessions with her in northern Jersey, plenty of DFK, nothing mechanical, very passionate. The only downside I could see was that she tended to revert to lazy positions (lazy K9, no ACG, etc.), But I think it's just more her style as she's more GND type rather than PSE. It's probably as you said, last day working and eager to finish up to get back home.
