He went up the escalator to the second floor, then turned right toward the bookstore.
After rummaging around the various aisles, looking low and high, opening and glancing at a few books now and then, he hastily left the place, much to the relief of the sales clerk who had silently followed him around and picked up and replaced his discarded books.
Then, catching the escalator to the third floor, he went into the movie house, glanced at the billboard, picked one at random, and purchased a ticket. The movie did not interest him much, so he switched between various movies playing on that day in the various theaters. Finally, he left.
Still on the third floor, he thought he might find it in the store that sold scented oils and soaps, but despite sniffing at a few sample bottles and disturbing the entire crew who were working the shift that morning by his frantic behavior and inane questions, he did not find it there.
Descending down the escalator, he paced the lower floor, peering anxiously in one window after another, but somehow nobody seemed to be selling it.
