OMG what a nightmare!
Almost had something similar happen to me. I was driving down the road, and I noticed a lady was stuck in her own driveway. Turned around and backed my pick up truck down the driveway and said I would pull her out.
She looked quite embarrassed, and hooked up her end of the chain herself. (I think it was an ego thing.) Took her quite a while, however, and she was getting very frustrated laying on the snow trying to find a good place to hook onto. I don't know what she eventually found, but when I pulled her out, there was some damage to her plastic cheap bumper. Nothing serious, because she came out of the stuck place quite easily, but she was not too pleased about it. She didn't give me any grief, but I could tell she was kind of mad at herself.
Said that she was planning on buying a 4 x 4 pick up truck very soon! LOL
I left feeling pretty good about it, thinking that I was the catalyst for her getting a different vehicle that she should've had a long time ago.
