Way back in my aerospace days, the guy at the next desk had a casting
he used as an ashtray. (I said this was way back.)

Drifting OT to talk about the days of smoking in the workplace

When I worked as a computer operator not long ago, the master console
keyboards were the same ones used by many generations of operators before
me. They were all stained yellow from the cigarette smoke. My supervisor
(who was working there back then) was talking about the 'good ole days' when
they had an ashtray next to every keyboard.
