Russians drink anywhere and everywhere. Including cops themselves. Polish and Slovaks too. Ukraine has war related prohibition, other then that? Where exactly eastern is it not allowed (or not completely normalized to the point locals would be surprised there is such law)?

Maybe they just don't follow that law, but public drinking is apparently illegal in Poland, Romania, even some cities in Slovakia apparently. Supposedly the police in Poland take a strict approach? (See wiki article "Drinking in public / By country")

> Eastern parts (except Czechia)

Which "eastern parts"? I've never seen that rule here, but have seen people drinking in public. Do you know that or are you just asking AI to confirm your biases?

My biases were that Eastern Europeans like a drink, I was surprised to see the laws. I already knew about Nordics and my hometown, Glasgow.

Public drinking is generally illegal in Poland ('police take a strict approach'), Romania, Lithuania, Slovakia (apparently not enforced in Slovakia).

Well, at least the Finnish laws against it aren't enforced at all and public drinking is very common. Judging by what I've seen, it seems to be the case in Sweden too.
