I had that happen to me in a company vehicle. It was freezing outside and 3 am in Greeley Co.. I was sitting in the car waiting for it to fill up. This guy comes from only God knows where in the worst part of town and bangs on the glass to let me know fuel was pouring out. After giving me a near heart attack, he pulled the pump out smiled and walked off.
again to the stranger in the night only lost about a 1/2 gallon.
