He only had to go down two levels. It felt crazy, taking the express two levels. What the silo needed was stairs. There were so many times he just needed to go up or down a single level and found himself waiting five minutes for a blasted lift. It made no sense.
The irony- in the silo with only lifts the occupants wanted stairs and in the one with only stairs they could’ve done with elevators. Perspective is very important.
