Re: Smoking
I recall smoking rooms on offshore oil rigs and platforms. Always inside as smoking outside was a definite no-no (smouldering weed and flammable gas don't mix well)!
Whilst the smoking rooms would usually have fairly robust extraction systems, you only needed to walk in and breath to get your nicotine hit. There was one which was a glass cubicle to one side of the mess - sometimes so full of smoke it was difficult to see how many people were in there.
