I feel ya man, something very similar happened to me last summer. I had been looking for jobs, I went to the mall and dropped of my job application at a local Suncoast. Got into my tour Looked behind me to see a Taurus pull into a spot across the row from me.. Cool, I can back up now, So I inch out and turn to my left and right to see if anybody was coming in either direction, there wasnt so I eased the clutch out more and turned back around to find the taurus had decided to find a different spot as I was backing up... Kind of my stupid mistake because I should have looked sooner. The guy was very nice and there was hardly any damamged, a light scrape in both of our cars. We decided to just forget about it and go our seprate ways, very nice guy.
