Damn so it's actually a problem to be intoxicated alone, even if I drank the alcohol at home and then went to the public like to the beach?
I'm not talking about being disturbing to people but just slurring words and being euphoric where it's obvious that the person might had some drinks.
I mean how do you handle going to parties then if you have to get back home by tram or Uber and it's obvious that you had drinks? Are people actually doing something illegal if they commute home drunk (of course not driving themselves)? After I went to a club I usually drive home by bus or tram but of course I mind my own business and am calm or chat with a friend. So people might not even notice that I'm drunk but even if they did it would be completely normal and it wouldn't be illegal.
And addressing the music thing: Here (at least in my city) there are known places in the center where everyone knows that young adults go there every weekend to party. It's basically an outdoor party each weekend in the summer of maybe between 100 to 300 random people with JBL speakers etc. It's not a designated area or an event or so but they just let the people have their fun. It's just random people coming with alcohol and having fun. Doesn't this exist in America?
