Before they banned smoking in the planes in the mid-80's my father had to sit there putting up with some jerk-captain's smoking and being miserable in the 727. Nowadays, FO's are such losers they sometimes expect the captain to do the walk-around even though its the FO"s be default, what wimps. Many airlines allow the FO to bid his trips to avoid a certain captain, but the captain himself can't choose not to fly with a certain FO! SMoking was bad, doing teh walk-around isn't that hard...
