Yeah, I think that event in Berlin was one of the examples I had in mind as far as news-grabbing super-spreading.

Still, I can't really tell how much that crowd's attitude is indicative of the rest of Germany or even of other Berliners.

I'd say not at all, but then I live in the north where we have very few cases and at least in my city there is no mask compliance problem at all. I tend to hear worse stories from further south.
