Arthur had never been good with elevators, even if he was taking it alone. Unless he was the very first person who entered it after the daily cleaning, there would always be a trace of people's pheromone. After a whole day, it would be unbearable, no matter how good the installed air purifier was.
Because of that, he always took the stairs if it was less than ten stories high. Yeah, he'd rather climb ten stories of flight rather than use the elevators, burning some calories while at it. Even while going with others, he would take the stairs and wait for them near the elevators. People would mistake him for being claustrophobic because of it.
Most just chalked it up to another one of Arthur's quirks, but they would still ask questions first. This was the rare time Arthur didn't have to deliberately separate himself or ask to use the escalator first. Eugene didn't even glance at the elevator, even though it had just arrived when he walked past, and only two people went inside.
