It's not all money and stanky clean up, I saw a video highlighting one guy, round the parts of this site I think, may have been from Reddit, but he was trash-manning it up as is his profession, and a man hastily threw something into his bin, quickly going back inside his house.
When trash-friend got to that house, he peeked inside. It was a fucking pristine laptop (???). He tried to stealthily take it out and put it in the front area of the truck, but the guy came back out a minute later and got all antsy, interrogating him if he'd taken the laptop. He said he didn't mess with it, it's in the trash. After work, he turned it on...(??? intensifies)....As you likely guessed, the guy who tossed the laptop was a kiddy diddler, trash-friend reported him to the cops, and all went well enough.
Trash-men can see whatever shit people want taken to be buried beneath heaps of trash to be left for eternity. Keep that in mind, however rare it may be.
