Is this common in Denmark?
No, it is not. It is just a random sentence, no one drinks tea along with pork.
Not a Danish thing, i mean we do eat pork, and some drink tea, but its not like it is a tradition, to do both at the same time.
Confused about when to use the present continious.
You can use whichever sounds best in the English version. In Danish they are not disinguished, you always use the present.
why would you drink tea whilst eating pork that's so weird
No need to repeat the "are" in the English translation, I think.
Yep, no need and accepted with just the first are, as should be
Do you mean eating a dead pig and then drinking tea like sociopats?
Fortunately, they do not eat "Schweinekot". Haha. :-)
