"On return from Gran Canaria".
ie sector 2.
How was this not spotted and acted upon on sector 1?
Hard to credit that she was over the limit 11-12hrs after coming on duty (few people I imagine drink heavily and immediately go to work as cabin crew) so the implication may well be that she was drinking from the bar - ie theft too.
The poor Captain was put in a hideous position. Do nothing and be complicit to the crime or do his legally required duty and find himself reviled in the crewroom. Sadly it's his duty to act, a part of being a Professional.
Compassion is probably the right approach in the crewroon at report time but doesn't enter into it once actually on duty and has no place in such an event unless the Captain chooses to abrogate his Professional duty and become an accessory to the offence.
