responsibility is on the server and the establishment, not the recipient.
This is where we disagree. I agree that the server should not “over serve” as a matter of the profession. But ultimately it is the responsibility of the drinker to not “over drink”.
This isn't about "over drinking". If an alcohol manufacturer marked the bottle as 60 proof but it was actually 120 proof, they're liable.
In the case of airplanes, airline management decides they want to save money by not pressurizing the cabin to the proper altitude - which means that alcohol hits drinking passengers faster and harder. They know it but do it anyway. That's on them, not the unsuspecting passengers.
We can disagree but the law doesn't. Lawyers get charges dropped against drunken passengers all the time because the airlines regularly underpressurize the cabins.
