Denmark is now opening up, but only when you can present "papers" (digital on your phone) that you have been vaccinated or tested negative within 72 hours.
This is required for going to restaurants, hairdressers, gyms and the like.
Damn, never thought I would have to live like that in my lifetime. People are docile, brainwashed and just happy the restrictions are being "lifted".
This is a prime example of the Hegelian Dialect: Problem, Reaction, Solution.
Have no idea, but the government propably has that covered. They recently passed a very draconian new "epidemics" law.
What basically happens is that you just don't get to enter these premises.
