One of my jobs as an Undercover Operative, when I was a Private Investigator, was working in an optics lab where gold was supposedly missing. It was soon determined to have been only an inventory error. When I left, the separation slip noted that (as I falsely claimed), I was "going to Waterloo University." The slip gives my job as "cyl. operator"— a polisher of eyeglass lenses in fact, in which role I wore a lab coat to keep the thick, rouge polishing liquid off my clothes.
