Yep ! Drinking their own alcohol !
That would be it
Cabin Staff blameless !!
Totally illegal, but hey !
Must be great living in a life where everything is black or white? You're correct, drinking their own alcohol is illegal; do you think these idiots care one iota? Do you think they are consuming it so blatantly that everyone and anybody will see? I have been involved in so many of these types of incidents, thankfully the majority brought to a much more subdued outcome, that I've lost count. Its become an endemic part of society and unfortunately for crew it becomes their problem to manage. Whilst I'll agree, not everyone can be blameless and some can handle situations better, I very much doubt this crew kept plying people with vast quantities of drink on a 4.5 hour flight.
