I've seen dipshits like this before. What they're usually trying to do is dumping shit on someone else's property and then trying to get you to pay them to come get their own shit that they dumped there under the assumption that anyone would be that dumb to do such a thing. They're also usually this stupid and out of it. There was a case here locally of something similar where a guy with a professional towing truck would tow vehicles into neighborhoods and then leave the cars in front of people's houses and try to say that they had to pay him to pick it up because they "asked for the car to be dropped there or some shit" and it was so retardedly illegal that they were sued by the city in about 10 seconds.
