Why did they even bother to purchase rolls of different colors?
Stolen supplies from a construction site maybe?
You'd be surprised what can lay around. I remember as a teenager, there was a LOT of industrial construction near my house and out of curiosity I explored those sites at night with my friends.
We'd find rolls of electrical cables, boxes of nails, and even blueprints!
Though I guess these days they lock up everything.
