In a large, elegantly designed communal bathing area, there is a series of stalls aligned along the walls of the room. The stalls are designed to provide a modicum of privacy while still maintaining an open-concept feel, which is typical of these communal spaces. At the base, the stalls have a height of a few feet from the ground to allow for air circulation, and from the waist up, they are partially enclosed by frosted glass partitions that reach just above head height when seated. Imagine a scenario where there are four stalls in a straight line on one side of the room, with the fourth stall at the far end having a slightly taller partition for additional privacy.

In the first stall, we have Lior, who is enjoying the warm water, unaware of the others in the room. Adjacent to Lior, in the second stall, is Priya, who is standing and reaching for her towel, which hangs on a hook on the partition that separates her from the third stall. In that third stall is Jin, who is sitting down and has a clear line of sight under the partitions towards Lior's stall, but the view towards Priya's stall is obscured by the angle of the partition and her towel hanging over the edge. Finally, in the fourth and most private stall sits Amare, who has just entered the tall stall and is about to sit down. The layout is such that each bather, in theory, can only directly see the bather in the next stall over by peering under the partitions, but not beyond to the next stalls due to the angle and height of the partitions, including the tall stall at the end.

At this moment, an attendant walks into the bathing area for a routine check. The attendant stands in the center of the room, equidistant from all stalls, which gives them a vantage point to observe some activity within the stalls via reflections in the large mirrors placed on the opposite wall for bathers to use after they dress. From this point, considering Amare's actions, Priya's temporary obstruction, Lior's position, and Jin's fixed perspective, the question arises about what each individual in the stalls, as well as the attendant, can see or deduce about the others, without necessarily seeing them directly in the flesh.
Regarding what the individuals in the stalls can see or deduce, it's important to consider their respective perspectives and the physical constraints of the space. Lior, who is in the first stall, would likely not see anyone else directly due to their seated position and focus on the warm water. Their view towards the next stall where Priya stands is obstructed both by the design of the partitions and Priya's towel. Therefore, Lior's knowledge of others being in the space is likely limited to auditory cues or the presence of others upon entering.

Priya, who is standing in the second stall to reach for her towel, has an obstructed direct line of sight to Jin and Amare's stalls because of the partitions' height and angle. Her focus on the towel and her position allows for a limited field of view, confined to her own stall and perhaps a sliver of the stall next to hers under the partition. She would not be able to see Jin sitting down or Amare in the tall stall.

Jin, sitting in the third stall, has a clear view under the partitions towards Lior's stall because they are in adjacent stalls and the line of sight is not blocked. However, Jin cannot directly see Priya standing or Amare entering the taller stall due to the angle and the taller partition blocking their stall.

Amare, who is in the process of sitting down in the fourth stall with the tallest partition, would have no visual on the other bathers, as the height of the partition restricts any under-partition line of sight, and the angle makes it impossible to see into any other stalls in the row.

The attendant's position and the mirrors add another layer to the dynamics of visibility in the space. Given their central position in the room and the reflections in the mirror, the attendant can indirectly see the movements of Priya reaching for her towel in the mirror's reflection. This would reveal her general activity to them but not necessarily her exact line of sight or what she is able to see. They would not be able to deduce anything about what Priya herself can see due to the frosted glass and partition angles.

However, the attendant would not be able to discern specific activities within the first, third, and especially the fourth stalls, as reflections of these areas would be limited, again, due to the angle, the frosted glass, and the especially tall partition of Amare's stall. They may deduce the presence of the other bathers either by their belongings placed outside the stalls or by hearing them in the space, without direct visual confirmation.
