Nazis picking up trash?
It just goes to show, Arbeit macht frei.
Sorry, that joke's in very bad taste. But what can you say about this. Do they wear black uniforms and swastika armbands as they march along the highway with their trash-collecting equipment?
Yes they did, and that's why Suhayda was upset. These fools decide they want to do some humanitarian garbage instead of fighting for the cause, and so they start picking up garbage on the side of the road. These aren't real Comrades, just some wannabes in costumes.
