That’s super cool of them. I guess fire is one of those things where jurisdiction doesn’t have to be exact. And with the lack of physical border there, they could easily just hop over and do their Dutch colleagues a favor.

Emergency services work cross border lots of times but I had never seen it in action. They were super fast too, far faster than I thought was even possible and their dutch colleagues weren't all that far behind. They managed to save the surrounding buildings but the building where the fire started was lost.

I mean they were possibly going to help anyway or even physically closer. And I imagine that sitting around in the fire department does get boring, something to do occasionally is welcome :)
