Heading down

 

 When taking that last picture, I noticed the security guard letting someone (the person visible in this picture, presumably) go down the escalators. So I went up to him and asked if I could go downstairs, which led him to ask me if I was looking for the restrooms, to which I'm pretty sure I responded something along the lines of "Uhh... sure". Despite that less-than-convincing response, he did let me go down, allowing me to get a glimpse of the even-more-deserted basement level of the store.
