I think the "The assistant turns to face you through the screen, raising one hand as though to test the surface from its side." message happens when you're etheric. At least so far I was getting it consistently while etheric, then stopped seeing it after sobering up, until I took some more Eclipse. I tried interacting with the sales assistant while etheric a bunch, using an immersive visor and dropping my hardening to 0 to see if I could let it get through, but so far no change in that messaging.
