I experienced that in Copenhagen when I was at an ATEEZ's concert.

I don't think that is a Danish thing (there weren't only Danish fans watching them perform), or I don't know, I don't think I have been to many concerts and stuff in Denmark.
I also don't think I have experienced people stomping their feet in concerts in my country.
