Assuming that waitstaff did threaten violence, there's got to be way more to the story. The worst waitstaff I have ever encountered in my travels were indifferent, and those episodes weren't in Norway. For someone to go ballistic on a guest would take far more than sending a dish back or being a royal PITA.
