actually, it's the opposite. I worked for the airlines 24 years. I now work in mental health and understand people a little better. Some people have back problems can't sit that long. Some people may take their shoes off because they think they're at home and can do whatever, the same way some people go to the grocery store in pajamas.
saying Asian Airlines repeatedly score higher in terms of customer service than US airlines is a statistical reality. It's not just airlines, though. Asian cultures, especially Japan- score higher in all service comparable service industry.
i am the guy who sits in the chair and observes everything. I know how many seats away from the nearest emergency exit. I have made mental assessments of who is likely to panic or be helpful. Most people flying probably have a bus paradigm, and it needs modifications... it's also true, this airline person's list is a pet peeve list, not something enforceable by militant airline Nazis, not a social construct that all humans should be living by, or these would be the rules listed in the seatback pocket. airlines have made the airplanes uncomfortable, and packed people in to increase revenue, not make your flying experience enjoyable. And it shows in how they pay their employees, and the kinds of service employees provide.
