I guess if a man propositions a drunk woman in the elevator of their hotel at 4 am, and the lift is going up towards their rooms, there is sexism involved. She's unable to give consent if he's looking for sex, and probably doesn't need coffee in his room. I perceive it as him making assumptions that she might agree. Unless he was the type who wouldn't take advantage of a drunk woman, should she have said 'yes' to coffee? But then, if he wasn't the type to take advantage, he wouldn't have asked her in the first place?
