A side-effect of certain media consumption

Whenever I read or watch light entertainments set in Britain in the Jazz Age through, say, post-War periods of the 20th century (Jeeves and Wooster, Campion, that sort of thing), I end up really wanting a brandy and soda.

Fortunately, I have brandy, and I have seltzer, so it's okay. But, man, the "lighthearted upper-class young man" character-type sure drinks a lot of brandy and soda.
