would you be happy to lose your livelihood because a young, cabin-crew member decides to smuggle that special 150ml bottle of expensive shampoo in his/her cabin bag?
Wouldn't happen at my airline, we have slightly more responsible folks in the CC ranks.
IE; They do what they are told, or are dismissed accordingly.
Simple as that.
And, yes, if I don't like their performance, the CC manager sends 'em a don't come Monday letter, pronto.
At an outstation?
They are dismissed promptly, and can find their own way home.
Therefore, they comply with the rules in force.
Case closed.
