I was on the access list AFJ. You'd have noticed if you weren't in your farter all the time. Didn't see any big chap smoking though, just a big chap muttering something about deep sleep or sudden death.
We had a big no smoking period on VALIANT in the 70s: best way of getting around it was to sit by the air compressor inlets in the motor room and chew lots of spearmint gum. Problem was when we surfaced, there was always a big smoke ring when we hit the roof !!
