In a very large room, there was a long sidewalk slab made of gray marble and beautiful thick brown wood rails. The bridge was not hanging from the ceiling or supported by columns, but it was floating very solidly in midair. The marble sidewalk was at perhaps 9 feet wide.
In the center of the sidewalk walked two women. One was young, the other older. They walked side by side. The older woman was an escort to the younger. They walked along in the very center of the sidewalk, nowhere near the rails.
The end of the sidewalk featured a counter arrayed perpendicular to the sidewalk, with a partial wall directly behind it. There was another woman behind the counter. The escort delivered the young woman to the woman behind the counter, and they both walked around and behind the wall.
