Bethesda would need to make sure that all the smokers in the bars go outside to do so, just to keep it in touch with the real world. My fragile mind wouldn't be able to comprehend the exposure to such lavish activities, and it would most likely spur me to go smoke inside bars in real life too, cause obviously I won't be able to separate a computer game from the real world.
God bless the sensory rating system.
EDIT: Sorry, sarcasm was applied. I was fired up from the 'Kids in Skyrim' discussion.
