I am concerned that during the safety announcement that the sound was either drowned out by plane noise or people talking. Also people were not even trying to listen or bother looking at the safety brochures. There does not seem to be any emphasis on making sure passengers understand the need of immediately vacating the plane and how to open the doors and how to use the life rafts if an accident occurs and what to do in an emergency. I think I missed seeing something on the plane screen during meals etc. Used to enjoy the funny nonverbal short skits. It might be something to look into to provide small disinfecting wipes on the meal trays and mention to staff to explain use of them.
