Alcohol is one of the most STANDARDIZED substances on the planet. 5% at 500 mil is always going to be the same amount of alcohol. Of course it's going to be predictable and socially acceptable. Try doing any other drug and you have no clue what you're getting, even if you get it from the the same source time and time again.
The predictability is a FEATURE. And btw, it's not boring at all.
You are conflating boring with predictable.
