A friend from Yugoslavia told me about his job there. Their lunch room looked like a grand cafe with every possible kind of liquor and a variety of beer on the tap. Around 11 am some of his coworkers had a few beers, in the sun, in front of the building. Around 1 they had some whiskey or vodka etc. At the end of the work day some went home, others stuck around. They had a few more drinks, some went home, others went out to eat together, some went home after dinner, some went back to the office. He regularly got very drunk. Sometimes he would make a row of chairs and sleep there. 7 am his boss would be the first to arrive. He was always happy to see someone was already there and made coffee. They sat around and chatted some more and he would start his shift an hour early (not paid ofc)
It wasn't that everyone got drunk at work every day, some more often than others, some rarely which made it kind of a special occasion if they stuck around.
He had the same assignments as his coworkers but completed them in half the time. Sometimes, at 11 am, he would just continue drinking beer while sitting in the sun and go home an hour early.
The funniest part was that they mostly talked about work. It was one lengthy extended meeting till 1 am, if they had some kind of deadline they would just work in their spare time while drinking (without pay)
No culture is strange until compared. I drink 2 liters of coffee, smoke a lot and consume lots of sugar. This is perfectly normal here.
edit: it was a desk job
