If they did so with any semblance of professionalism, the stories wouldn't be very interesting.
I once interviewed with a company where it was apparent 10 minutes in that it wasn't work I was interested in (they were a stealth mode startup, so my preparatory research didn't tell me much). I made my interests clear when describing myself, and it was apparent on both sides that there wasn't a good fit. We mutually agreed to cut the interview short. Not a very interesting story, but no bridges were burned and nobody's time was wasted. I'd expect that most such stories are similar.
