From a passenger's point of view, it seems to me that the sentences are appropriate.
The Captain is just that The Captain , not The Pilot and he is the person in overall charge of the aircraft, crew and passengers. IMHO, he ignored at least some of his responsibilities, although it is possible he was unaware of the CSD's level of intoxication. But was he proposing not to leave the flight deck for so much as loo break during the flight, knowing that the First Officer might not be 100%?
Equally, CSD's are responsible for rather more than pushing a trolley! Like everything that happens the other side of the locked cockpit door! Not least getting the passengers off in the unlikely event of a problem, dealing with sick passengers (heart attacks etc). Rare but they do happen.
CSD's are by definition not juniors and (again IMHO) this one really should have known better. I haven't been to Norway for a few years now and it's a great country but (ignoring the precise legal limits for a minute) they're not exactly famous for their tolerance towards booze when driving cars or flying aircraft.
As it happens, I come into contact with quite a lot of crew and their individual attitudes towards work, alcohol intake etc vary hugely. One of my best mates is a Purser and I have rarely met a more dedicated, conscientious or responsible! person.
Bit boring when they have two beers then head off to bed at 10pm cos they have an early pickup but contrast that with those out partying till 3am and I know who'd I rather have looking after my safety on a flight. Or that of my offspring flying unmin. Or my mum. It's not rocket science I'm afraid.
My two pence worth.
