Funniest line I ever saw on Youtube, from a Dutch, not Danish, guy, talking
about a video of rude TSA/customs in USA airports: "You Americans need to unionize! We wouldn't go to work in the morning if they treated us like that--we'd shut the whole country down!"

I don't agree with the OP.

Denmark doesn't have some special hold over decent security screening; almost every country in the world, except for the US, has polite and professional screeners. While there may be one or two individual exceptions, the vast majority of countries don't have the paranoid and bullying tactics in regular use at US screening checkpoints.
