Oh yeah, the "talk and walk." I often notice that in TV and movies too, and while I get the purpose on the dramatic front and for visual interest, it's definitely one of those breaks from naturalism that doesn't always fit with the rest of what it's in.

Here, I felt like it stood out even more before there was no "walk." Wynn-Williams says the thing that needs saying and reveals her bosses'/colleagues' ignorance, and then the scene just ends, even though she's still in the room with those people, who presumably have a response for her—one that she presumably capitulates to, given how long she chose to stay with the company.
