Good point made above about Margaritas, wine and champagne. Status drinks.
It doesn't matter Shiv, it's the alcohol content and the volumes and actions that everyone sees. You might aswell be on a park bench swigging out of a bottle of buckfast or a naggin of vodka.
I don't see Business class travel or lunch at the Ritz, all that glamour fades into the background and the alcohol becomes the focus. Right now, contextually speaking I just see a drunk homeless person who doesn't know who they are who needs help before it's too late.
I'll be equally scathing and say that Siobhan has the personality type that she knows best and will flat out deny any help and tell the helper that they are the ones with the problem. (I've been in the helper spot).
