Despite the disorder, he knew where the decanters were kept, and quickly had his guests supplied with whisky. He'd put quite a lot of soda in Brianna's, but noticed that she sipped at it as though her glass contained ant spray, rather than the best Glenfiddich single malt. Claire, who took her whisky neat by request, seemed to enjoy it much more.
In the midst of chaos, the character displayed a remarkable familiarity with his surroundings, quickly locating the decanters to serve whisky to his guests. He showed thoughtfulness in his service by adding extra soda to Brianna's drink, but her reaction suggested she was unimpressed by the quality of the whisky provided, treating it with disdain rather than appreciation.
On the other hand, Claire preferred her whisky without any mixers and seemed to take greater pleasure in the drink. This contrast highlights the differing tastes of the characters and serves to emphasize their unique personalities and preferences in a lively social setting.
