Shibuya miumiu

This morning I took a picture of the shopping window of the local
shibuya miu miu store. I got fascinated by the disco style
"Schaufensterpuppe" (ode to Kraftwerk *chiiii*) just to realize that
it's forbidden. As you might tell by the batsu (crossed arms) sign of
the staff, who is standing next to it. It's a crazy world, here in
Tokyo. How does she think she can prevent me from taking this pic? Why
aren't you allowed to do so? Just to mention some of my questions that
struck my mind.
