Even when you’ve dressed inconspicuously, perfected the art of watching people out of the corner of your eye, mastered the skill looking like a student working on a school project, and basically become the awesome-sleuthy offspring of James Bond and Harriet the Spy…

There will still always be one security guard who hasn’t met you, suspects you’re up to no good, and shouts loudly from across the room (and in German),

Hey! Why are you following that lady and writing down what she’s doing?

Your German won’t be good enough to explain this one, so just walk – or run – away and hide in the staff lounge. The visitors can’t catch you there.
