Ah yes "security reasons"....probably his own security. Afraid of being caught signing on and working at the same time.

I've been told off three times for taking pictures. Once at JFK security.....a fair cop. Once inside a shopping centre in Stockholm and the other was at the sea end of the main runway at CPH.
I had some hours to spare so cycled there to take some pictures of the landscape and the odd landing aircraft. I was all alone enjoying the peace and quiet of this very pleasant area when I spotted an airport vehicle haring along the perimeter road towards my direction. That's funny I thought....wonder why they're in such a rush?
It braked hard and came to a sudden halt on the other side of the fence adjacent to where I was standing. A door opened a blonde female jumped out and proceeded to shout something at me in Danish. Realising - probably by the look of bewilderment in my face that I was a foreigner she pointed to my camera and angrily shouted something else....I soon got the message, put the camera in my rucksack and gave her a wave as I cycled off.
All a bit OTT if you ask me.
