When Stevie and David discuss their sexualities, Stevie states that she only dates men while David reveals himself to be pansexual. In real life, their preferences are reversed- Emily Hampshire is pansexual while Dan Levy only dates men.
The producers of Schitt's Creek have been coy about whether the show is set in Canada or the United States. In this episode, David and Stevie browse wine in a local store. This isn't possible in Ontario, Canada, where the episode is filmed: all wine must be purchased from special 'LCBO' government stores, or at the winery itself. (Not entirely true. Premier Doug Ford opened it up and wine can be sold at supermarkets and other stores, but even years before that some small rural towns like the one depicted in the show could attach a small liquor store to it) There are at least four stores just outside the Ottawa area alone.)
