On our residentials we have two guys in the truck a shoveler and a driver. Not the best setup in the world but it works. If they come out and move the car while we are plowing and shoveling, fine we do the spot. If they don't move it then, we revisit the location when we get to it. This is only to prevent forming an Ice block in the driveway, which is good for us and them. All of this cost is all figured into the contract, when we give them a price we ask about the amount of cars they have and where they are parked.
As far as take care of the rest of the landscape, I leave that to someone else. The first time they see us is when we put the stakes up, the last time they see us is when we pick up the stakes in April. I don't know or really care what happens from April to november.
As far as explaining the importance of moving the car to a customer, I just don't see it happening. A long long time ago I was plowing residentials, and there was one cutomer that had 3 cars 2 in the garage 1 out side. I asked him if he could park the third car infront of the grage so we could pile the snow where car # 3 was parked, because it was the only place we could put snow. Well there wasn't onetime where the car wasn't in the way. Needless to say I just stopped showing up to plow it because it was a pain to do it with the car in the way. When the guy found me getting a soda at a store he asked why I hadn't done his drive yet. I told him I quit doing it because he never put the car in the right spot, and to find someone else. He inisted that the next storm he would keep the car in the right spot. I told him sorry find someone else, and he pulled the same BS with them.
