Gender
Members of all genders are targeted in this film as there are themes and motifs accessible to all within the story.
Age
15 - 35 is the primary age target since there is some bad language that may not be appropriate for a younger audience. The story revolves around to young characters at the start of their careers so this may not be as identifiable for someone older either, at least not in the current stage their life, more than likely.
Taste
Fans of Musicals should find a lot to enjoy in Bathroom Stall, as it features many classic tropes of the genre and fans of comedies should also find something to like as it plays quite broad in terms of humour.
Socio-Economic Background
The Lower-Middle Class are going to find that they have the most in common with the protagonists as the story represents people within that demographic.
Employment
There's certainly going to be an extra level of enjoyment for audience members that also work within the white collar/office field as most will say they can relate to the situation the central characters find themselves in.
