Although the title of this video claims the fire was caused by a cigarette, we can clearly see that neither person was smoking. I would also point out that the outside temperature is cold (i.e. they are wearing winter coats) and the one person has both hands in his pockets. 9 seconds into the video he pulls one of his hands out of his pocket and reaches toward the nozzle for some reason. As soon as his hand is near the nozzle we see ignition. The person pumping the gas makes the critical mistake of pulling out the nozzle and we can see the results. The positives out of the video is the fire extinguisher demonstration done by a customer. Using a dry chemical extinguisher he quickly and easily extinguishers the fire in LESS THAN 10 SECONDS!
