Yeah if you have expectations you need to let them know ahead of time. I have never plowed so I don't know the specifics of that industry but if you have non standard expectations I would try contacting the office and ask what is the best way of communication that to the driver. If your requests are kind of extra I would also consider meeting the driver when he gets to your house and talking to him as well and at that point offering a hot coffee or something. If you're waiting until after and complaining it's creating a problem for the company, possibly getting the driver in trouble, and probably costing them money so that's definitely not the move. What are they doing that's wrong anyways?
