The passenger has probably heard airline safety instructions dozens of time before. Is there that much difference between them? Frankly it surprised me that the crew made a big deal about this situation.
I fly on average 50-80 times per year. Many of my flights are on the same type. However, I always give the cabin crew my full attention. Furthermore, if I am in the emergency exit row I always familiarize myself with the opening procedure so that I am mentally prepared. Same when not in an emergency exit row. I check my surroundings and count the rows to the nearest emergency exits in the event I have to navigate there in total darkness. How many people staying in hotels familiarize themselves with the quickest route and location to the emergency exits?
Sorry PastTense, there is NO excuse whatsover for the attitude of these passengers. I hope Air NZ will ban them for life!
