Wow, you guys get hit up a lot for stuff! We don't have people knocking on our doors here except for Delivery guys, once and a while Jehovah's Witnesses, and very rarely truck drivers asking how to avoid the low RR overpass near us. Seriously, we live in a rural village and no one bugs us. But, one time when a North Jersey (very important distinction-- they are "slicker" and do shit like you describe) company did a home inspection on our home for sale and the next day our whole row of young strawberry plants were GONE. Dug up and just gone. Of course they said they had no idea how that happened. Who the F would do that? It takes years for the plants to bear fruit. Anyway, sorry for all the taking advantage of your generosity. I would be tempted to put up a sign : "SORRY WE ARE WORKING AND BUSY. THE DOLLAR STORE HAS WHATEVER YOU NEED FOR YOUR CAR."
