The crew mentions pulling the toggle if the slide does not deploy in the safety briefing, and the cards point it out too, so there would have been little excuse if the said Woman opened the door and the slide did not deploy automatically.
If you don't listen to the safety procedures because you are distracted by looking outside, reading, sneakily listening to music or sleeping because you have a "nothing will happen to me attitude" then you have no leg to stand on if something does happen and you try and blame the Airline for what happened.
