You situation calls for a 12 pack of Bud. I’ve had the same experience. Three times the plow guy sealed the opening I created. I picked up a 12 pack, stood in the street the next pass, and got him to not only clear the drive, but move a huge pile of snow so there would be room for the next storm. He never blocked the drive again.

Ahhh! Bribery. I like the way you operate!
