I remember sneaking into the elevator, waiting inside it until it began traveling upwards, then discretely using the service stairs which smelled like laundry detergent. When I arrived on the very top floor I discovered it was a gym, I tried my best to slalom between the security cameras and the fitness machines. The panorama was amazing but the train station took my attention; I spent some time looking at all these small commuters waiting for their trains that will take them home after a long day at work.
