Problem is every drunk I have ever met says they have always been well behaved. How do you know whether you are or not?
Quickstatus, I hear and understand your point. Alcohol is well known to cloud peoples memories....
I am totally for the denial of service to coughholes. I do not enjoy being anywhere, be it a flight or a restaurant or anywhere, where there are tools that are drunk and impacting on me. Raucous behaviour, foul language, etc. I simply deplore that.
But I also do understand (and COMPLETELY agree with) the other side of this - as expressed by Max Samuels, etc. That this is a hard area and there is actually much pleasure to be gained from getting tipsy on a flight that does not necessarily mean an impact on others.
I do drink. Profoundly. Amongst a myriad other things, it allows me personally to escape the restrictions of Asperger and actually be able to connect with fellow pax. It allows me to relax and really super-enjoy whatever travel I am doing.
As so many things in life are, it is really the person, not the influences, that make them a great or horrid pax.
To answer your question, the "How do you know" thing - regarding if you are well behaved. I can answer this only from my own self-experience. I am a professional in this regard - I do not trust my own perceptions. But my record is very clear. In much over a thousand flights, I would have been legally drunk on almost all of them. I have never been refused alcohol, nor suffered embarrassing moments. Despite on many occasion being extremely hammered.
On the contrary, I have been blessed with innumerable instances of the flight staff loving me - bottles of champas to bourbon being gifted to me because the staff thought I was a great and positive influence.
I think this should enlighten the real situation - it is not about alcohol per se, it is about individuals.
And I would also like to offer that this alcohol-problem thing is much enhanced in Aussie. A negative cultural thing..
I lived in Colombia for almost a decade. their alcohol rules are extremely relaxed. You can walk down the street imbibing a bottle of rum, if that is your fancy. But in TEN YEARS of living there I did not see the problems that it only takes a weekend in Aussie to see. You do not suffer loud mouths, you do not have the omni-present danger of cowardly punches outside nightclubs. I have never, EVER seen inappropriate behaviour in the lounges there.
This leads me to believe that alcohol-fueled problems are, in Aussie terms, more about society than the actual liquor.
