I think the question is very good and very valid.
I don't drink a lot at home, but put me in a lounge or on a plane and I am TERRIBLE. No joke - if I'm on an international flight, I don't care if it's breakfast time at the lounge, I am going to drink.
It is REALLY hard to turn down free booze.. not sure why. It's not like I can't buy it at home. Plus it seems like everyone else is drinking too. Yikes!!! I'm a grown adult with a well-compensated job and I'm worried about missing free booze?? And the "everyone else is doing it" mentality? Downright embarrassing....
