Superstition : Cigarettes.
The superstition that it is bad luck to light three cigarettes from one match appears to have originated during the Boer War. It was said that a sniper could spot where men might be as the first cigarette was being lit, take aim as the second was ignited and fire with deadly effect at the third. Two lights were enough for any group of men who valued their lives.
