Your CURIOSITY rises, prompting you to open up the paper. There's messy handwriting, and it's all smudged up with oil and cinnamon sugar. You can still make some words out, though, and it looks to be a schedule. At 10:something, "work!". At 5:something, whoever tossed this in had an extended quote-unquote lunch. At 8:00, they head back to work. At 11:00, something happens, and they clear the lobby. After that, the times become question marks and whatever happens at those times gets real oily. Something about letting someone whose name starts with S do his thing, and that's all they wrote.
