I know it's hard to see because this image is so small (as per this site's request), but the flyer placed under the car's windshield wiper reads "TIRE SALE".
This strip is somewhat based on a true story. I work at a gas station here in St. Cloud and one day someone walked up to the store and asked if we had a tire jack. He had gotten a flat tire on his way into the parking lot and needed to put on a spare. Just as I was about to offer him one out of my trunk, who should drive up but a local tire company van. The man with the flat bought a new tire on the spot and was on his way.
Coincidence? I think not.
