A Surprise Bag

Exploration Stage: Beauty Salon
From: Detective
Description: I see another oil stain near that canvas bag. It looks too plain for this fancy salon, so I think the culprit left it here. What kind of scheme is this, anyway? Let’s see what’s in the bag.
Completed: As a coffee lover, I immediately recognized these as green beans. They don’t make for a great drink, but there seems to be one in this cup... Nope, it’s oil again. Who needs coffee-bean oil?
