I found this to be the same reason why many of my fellow shipmates smoked during my time in the Navy. It was a kind of pre-watch "bonding" session of sorts...We'd smoke our cigs, grab a quick bite from the galley, then relieve the watch...our pre-watch smoke was a kind of "shoot-the-shit" before we had to be serious and formal operators.
