Question about the episode:' The Legand'

[Auntie]

Just have a couple of questions about the episode of 'The Legand'. In this episode, why was it that no one said anything to the father's friend 'Tip' when he was smoking in the living room (and in the episode of 'The Carnevale' they gave the young woman a 'look' when she lit a cigarette at the kitchen table). Also, during the scene when they were all singing in the living room, was that champane John was drinking or just water?
