If the airlines and airports insist on selling us booze at every possible opportunity, I think the degree of shock they can muster when someone goes off on one must be somewhat limited. Everyone has the responsibility for their own actions, and short of insisting on sobriety at all times there's not much that can be done. I feel for the cabin crew who have to display the skills of a professional barkeeper as well as being diplomats, department store sales staff, waiters, medics, childminders and... now, what was that other thing? Oh yes, in charge of the safety of hundreds of strangers in a very variable situation.
I'm not sure that those areas of the world where alcohol is banned have a much better safety/customer relations record, tbh.
