just put this on craigslist
Do not call me Saturday expecting me to clear your driveway. It will take me about 12 hours to get to you, if not more. As a snow removal contractor I have responsibility to my customers who were smart enough to arrange for plowing in advance.
If you expect me to drop everything I'm doing, to go plow 18" out of your driveway, I will think you're a 12 year old prank calling.
You might not like what I'm saying. In that case you can call a hack to plow for beer money. He'll show up and plow your unmarked drive right into your garage. If he even has a truck.
