I was a meter reader from '70's thru to late 90's. The meter reader who had The World's Largest Bookstore on his route, sometime in the late 80's had filed a Health and Safety report about a black oily seepage on the floor in the meter room at the Worlds Biggest Bookstore, near the boiler room. He didn't know what the substance was or even how deep it was, so under the H/S Act he refused to read the meter. This initiated an investigation by the supervisory staff of the meter reading department. Two supervisors were very suspicious that the reader was just "pulling a fast one", as one of them had put it (there was an undertone of antagonism between management and employees at the time and H/S was a new concept that did not get easily accepted by the supervisors). The two...we'll call them Heckle and Jeckle went down in Heckle's car to investigate. Jeckle went in, got the manager of the Words Largest Bookstore and they went to the source of the seepage in the basement. It was later to be confirmed it was oil from a tank under the floor. But Jeckle, thinking he'd test the "waters", so to speak, decided to step down into the substance. Not smart. He sunk to his waste in oil. The manager pulled the supervisor out. His suit was covered in stinky black oil. Heckle didn't want Jeckle back into his car, as his lower body was covered in oil. They eventually got some garbage bags to cover the seats. They went back to the office and filed a report. Although it could have been a dangerous situation it wasn't. The oil did get cleaned up and the H/S Committee members (some management included) laughed about it later.
True story.
