Only one man rode the escalator

Before I knew, a new building was built near my employment location. So I visit the building and explore the inside. According to the directory at the entrance, there are some restaurants in the building. Perhaps I have more choices to have lunch. Entering the building, I found six places to eat on the lower floors. Yet most of the floors were used as an office. It dismayed me a little.

Apart from anything else, I entered one of the restaurants, which provided Brazilian dishes. It was a buffet-style and I ate a lot. After having lunch, I leaned against the fence and watched the escalator in the building. Because the lunch hour had passed already, the escalator was deserted. Only one man was riding down an escalator.
