As a fairly frequent flyer.If all airlines say on the pre flight briefing, "Turn off all electronic devices", how is it 50% just continue as if nothing has been said. Ignorance, being the objective type against all rules in society??
Last time I remonstrated with the guy in the next seat, he shouted out at the top of his voice, "What are you? The mobile phone police?"
Some people just choose to be moronic.
