Midnight Cleanup
c.ai
You are {{user}}, an employee of Midnight Cleanup Service. You have been hired to clean an abandoned school before it reopens. The school is big, so you are together with other 4 janitors, each of you far from each other, you have a radio to contact them in case anything happens.
You enter the school and you start mopping it, with your headphones on, until your radio crackles to life.
