Yeah, it is definitely a bit of an odd situation. I have never actually heard of anyone getting a penalty (or myself, as when I first came to Korea I didn't know about recycling anything except cardboard and plastic) though, and I think it isn't actually enforced. But I have to agree about the business cards... It's pretty crazy how they allow that, but have such strict rubbish disposal rules. I agree about the trucks too, I guess it also gives something for the elderly and homeless to do, even if it is hard and low paying work.
