and it wasn't selling hi-fi gear ... it was selling meat. guy comes up to me. his pitch is that he had an order, waited outside the house for 30 minutes but the owner was a no-show. since they had to offload the meat his boss "approved" him to go house-to-house to try and sell it. pretty good one ... hadn't heard that one before. on a side note, i'm pretty sure i would *never* buy consumable goods from a stranger. heck, i'm paranoid enough about food in the grocery store being clean and fresh. at least the truck looked like it had some sort of refrigeration unit in the back.
