The probably had never seen a computer until that day and hour. Just a bunch of privates from the military dressed in civilian garb. After the visitors left, they were marched out and it was back to border duty.
This is most likely true. Another video on the web from a British tourist that managed to get to NK on a tour showed something similar. He and his party were taken to a restaurant. The group, about ten people, were the only people in the restaurant. In order to try to make it less weird, the restaurant staff made food enough for every seat in the room, and served it, to a nearly empty restaurant, as if they were waiting for a large party to show up. But no one else ever came.
This is probably the same thing. They needed a data center, so they put some computers in a room, turned them on, and got some people to sit there pretending to work.
Third Person’s video is the video with the restaurant scene. It is a well worth the time for anyone to see.
“After the visitors left, they were marched out and it was back to border duty...”
I just got a great idea for having illegals earn citizenship here in the USA...
