I can feel your pain. Early on, I hated waiting in the car because I live where it is 95 degrees all summer long. So that was pretty miserable. In the winter it was okay, if there were decent people in the car with you.
However, the last few years, I loved just sitting in the car waiting. Because I hated having to knock on doors and talk to folks. That was dreadful to me, so just sitting was by far the better alternative. And plus I usually always drive, so I would sit there with the air running.
