Paul Ament could be a rogue.
One day David Pennycuick was expanding his knowledge by wanting to see what was inside a rectifier block. It was a small epoxy filled block with some components embedded in it. As he was industriously using a hot soldering iron to dig the epoxy out of the small box, clouds of smoke billowed from it.
Paul stood casually by with one arm on the bench, smoking a cigarette and glancing up at a smoke detector on the ceiling. Suddenly fire alarm bells sounded with a volume that threatened to bring the roof down.
Paul just pointed a finger at David and said “THATS YOU” and made a hasty exit as sirens began to be heard in the distance, leaving David rather stunned.
