The office has a bar and zero no-smoking signs
Don continues to treat himself at the office the next day, starting bright and early in the morning. He has one stiff cocktail before his meetings, a Bloody Mary during a conference with a client, and a celebratory glass (along with a fat cigar) after a successful pitch to a tobacco company. We also see him have three more cigarettes during the day. To his credit, he does perform a whopping two or three stretches with some elastic exercise-band thing.
Tally: 7 drinks, 8 cigarettes, 1 cigar, 1 mistress.
After finishing at the office, Don ends his work day with a flirty meeting to smooth things over with a female client. Cig and a whiskey.
Tally: 8 drinks, 9 cigarettes, 1 cigar, 1 mistress—and heading towards another.
