I remember this. Ashtrays were practically part of the furniture (especially coffee tables), even if you didn't have a smoker at home.
I vaguely remember living room chairs with built in ash trays (like how some have cup holders now).
And in the late 90s, being on a plane and the chairs had a metal folding door on the armrest that exposed an ash tray. Smoking on planes was already gone or going away, but the hardware lingered for quite some time.
As was passing out cigarettes and cigars to all the guests, didn't see this so much in the USA but very common in Europe even into the late 1990s.
Elementary school children would make ashtrays as gifts for Father's Day.
If dad didn't smoke, surely he had guests who did.
