I used to fix computers in Stock Brokers offices in the City of London when smoking was common, and I think that they were probably chain smokers. Inside those cabinets was a health hazard. Trouble is the tarry stuff glues up the dusty stuff resulting in thick layers of crud . . . glad those days are over !
