They get drunk alright. I'm one of those who rarely drinks, and if I drink I very rarely get drunk because I usually drink just one beer. ;)
I used to be young and reckless and did have my share of drunkard foolishness to go with it. But that's about 20 years ago now.
May be you're not alone, I used to get drunk when I was a teenager but now I dont feel like to see myself that way , just one or two is fine.(ahahha but everyone has to go through these kind of phases in life may be)
Btw hope you do accept Steem dollars for a beer other than BTC :D. thanks for your support man for a newbie like me. keep it up.
