In a large department store, there is a rectangular changing area divided into several stalls by partial partitions, which do not reach the ceiling and thus allow sound to pass over them easily, but are high enough to grant visual privacy to individuals when they are standing upright. Each stall has a closed front with a door that can be locked from the inside. In one of these stalls, Chizuru is trying on clothes with the door locked. Adjacent to her stall, but not directly beside it, Kazuki waits outside another stall where his friend Jiao is changing clothes with the door locked as well. 

The partitions are arranged such that if a person were to stand on a bench within a stall, they could potentially see over into an adjacent stall. To ensure privacy, the store has placed notices prohibiting climbing on the benches. Chizuru has left her stall momentarily to fetch a different size, leaving her door ajar, while Jiao remains in her stall trying on clothes. At that moment, Szymon enters the changing area and is searching for a free stall to use. Without knowing the local customs and notices about bench use, Szymon might consider getting a better view of the occupancy by stepping onto a bench.

What would happen if Szymon stands on the bench to look for an unoccupied stall? What could Szymon possibly see concerning the other occupants, Chizuru and Jiao?

Provide a short response.
If Szymon, unaware of the store's notices, decides to step onto a bench in his quest to find an unoccupied changing stall, he would be elevated enough to peer over the partial partitions. Upon doing so, he might notice several outcomes dictated by spatial geometry and the current situation. Firstly, because Chizuru's door is ajar, indicating that her stall is unoccupied, Szymon would be able to recognize this unoccupied stall without having to step onto the bench. Therefore, his action is unnecessary to determine whether Chizuru's stall is available.

Regarding Jiao's stall, since Kazuki is waiting outside of it, it's suggested that the stall is occupied, and there is thus no need for Szymon to peer into this stall either. If he did look over into Jiao's stall, he would see her while she is changing, as the partitions are designed to prevent such visibility from the floor level.

Furthermore, if there are other unoccupied stalls in the changing area, Szymon would be able to see into these as well from his vantage point atop the bench. However, his actions would constitute a breach of privacy for anyone inside those stalls and also go against the explicit notices set by the store. It would be expected that store personnel or customers, such as Kazuki or even Jiao if she happens to catch sight of him, may confront Szymon and inform him that he is violating store policy by climbing onto the bench for this purpose.

Therefore, from the bench Szymon would indeed be able to see over the partitions. However, he would see that Chizuru's stall is vacant without needing the bench, would intrude upon Jiao's privacy as evidenced by Kazuki's presence, and could potentially observe other occupants as well.
