How many times have you run from the car to the house or into a store in a thunderstorm? I am sure this gentleman thought it was no big deal, getting an item from his car and scooting into the house. He was literally seconds away from being killed.
Often it's up to you to notice the sky getting dark and the breeze beginning to pick up as a thunderstorm moves in. Even if you do keep an eye to the sky you could still be in some danger from a bolt out of the blue.
