Actually they DO, they do tell stories like this. Popular stories even!
But you probably don't watch a lot of hijinks comedy movies.
Movies like The Hangover (2009, 2011, 2013), Harold & Kumar (2004, 2008, 2011), Get Him to the Greek (2010), Eurotrip (2004),Dude, Where's My Car? (2000), Girl's Trip (2017), Joy Ride (2023), Date Night (2010), The Lost City (2022), etc.
A common theme in this is genre of film is people getting inexplicable, seemingly random, almost mystical boons as a reward for good deeds towards people who seemed insignificant in the moment but turned out to wield strange power within the universe of the film, or alternatively, inexplicable, seemingly random, almost mystical punishments for selfish deeds that harmed people who seemed insignificant in the moment but turned out to wield strange power within the universe of the film.
These films tend to take place in a "fantasy world" not in the sense of being supernatural, but in the sense of being a place upon which people project fantasies, such as a tourist destination like Las Vegas or New Orleans, or a special escapist vacation event like a bachelorette party or a road trip.
Watch Harold & Kumar Escape from Guantanamo Bay (2008). It is chock full of capricious fae-like (in a functional sense, serving the same narrative role that a fairy would serve in a legend, not an aesthetic sense) archetypes granting the protagonists magical (by which I mean improbable, outsized and absurd) boons in exchange for favors and/or meting out absurd punishments in exchange for perceived slights.
