I was waved down while driving by a man from Quebec in his late twenties who said his name was Fred. He claimed that he worked for an audio distributor, and that he had just received a shipment of home theater systems.
He told me that he had received 2 more speakers than he was supposed to pick up, and that because he was borrowing his boss's truck, he either had to sell them now or bring them back to his boss. He said that the last time this had happened, he had brought them back to his boss and his boss sold them for extra cash.
He said that even though they cost $3000, (the price tag was on the professional-looking box) he would sell them really cheap because otherwise his boss would get all the money. He was very enthusiastic and very believable- he even went so far as to open the box (which was properly sealed) and show me the equipment.
He showed me all sorts of "proof," like the receipt for receiving the shipment which had recorded 2 boxes less than he had in his truck. (he counted them for me) He even told me that as he was from Quebec, (I speak french, and indeed he speaks french like someone from Quebec) he didn't know many people and he wondered if I wanted to go for a beer sometime. This is asked me AFTER I had paid him $360 for the speakers, and he even gave me his phone number (which he "proved" was his by showing me on his phone profile page). His phone number, by the way, doesn't work.
He was very aware of how sketchy this seemed, and mentioned it several times, and went out of his way to show me anything that would convince me that he was honest- in short, he played his part very well.
