In the above video, move to the 18:00 mark. After the 18:00 mark, at some point, the dealer takes the shoe and empties it, shuffles, and has the player cut before the cut-card is reached.
You may be right but she left a bet out when she picked up her winnings so that should have made the dealer wait or ask if she wanted to play another round.
I agree. She said "thank you very much" and may have made some sort of gesture that led the dealer to believe that she was through playing (although the bet is still in the circle). Seemed perfectly natural to me.
