There was a flower smell in the washroom. Totally different from how toilets were used to be in the 2020s. When Kakashi peeked out of a toilet compartment, he noticed the polished walls, cement compartments around him, bright lights all over, the hand dryer, and rolls of tissues hanging from the wall near the golden sink.
Everything had changed since the last time he had visited the men's washroom. He stepped on the floor, well that was the one thing that had not changed, the tiles were as polished as ever.
Kakashi stepped back to make sure his shoes were clean. They were, and he continued walking on the tiles. He looked around to check for any person in the washroom, it was midnight so that least possible.
Then he looked for the cleaning robots, no janitors, no secretaries going home after creating their employer's next-day routines. The coast was clear, with only bright lights and silent walls.
