Definitely an indicator of time in history, smoking, cigarettes/ashtrays are a consistent figure in the film.
Wendy smokes, Jack smokes (but we never see him smoke), and cigarette machines are shown across the hotel.
Wendy smokes around stressful and tense situations, which makes logical sense for someone who smokes, but signifies her as weaker. Jack smokes—there is a lit cigarette resting in the ashtray during No.25— but we never see him smoke. He is in control.
