I'm working with a Denmark company remotely for a while now and boi are they fucking slackers. How are they keeping up their economy I don't understand?

I'm from... well, eastern europe let's say. An immigrant, ok? And in my world you have to fucking grind to get somewhere nice in life.

But my danish colleague can casually message me "I'll take a look after the gym" in response. And in my head I'm like "Fucking what? Gym? Are you fucking with me? It is middle of the day!"

But everyone else in Denmark office seems to be ok with it, and I understand there are culture differences, so I try not to overreact and do it all in my head.
But where is the line, right? Besides fucking midday gym sessions he is also just a slacker, not paying attention to stuff I'm asking him and so on.

I guess I just want to hear your stories of how you got pissed with other cultures.
