Hands up.............
All Cabin Crew who have never driven whilst using a mobile phone...............
There is no difference, it is just the general lack of respect for rules, regulations and authority that is modern living.
There is, however, no excuse for the lack of please and thank-you culture becoming evident by users of all services now days. I myself find a quick hi to the crew on boarding and a cheers on getting off, a natural, almost reflex action, be it an aircraft or bus. How do some people supress this?
