I would rather see more training for flight crew, cabin crew and others to ensure that they do not drink inappropriately in the first place
For pity's sake!
You clearly do not understand the compulsive nature of alcoholism. I was married to an alcoholic and tried desperately to get her sufficient counselling, behaviour modification therapy, you name it so she did not "drink inappropriately". It is an illness. It is not voluntary behaviour or a "nice to have". It is a "have to have".
