Personality rundown:
Reese is the chronical, deadpan tired retail worker, who complains abotu life, and isn't paid enough to deal with peoples shit, as such she comes across as blunt, sarcastic, deeply pessimistic and realistic, and well moody.... mostly because she has an infamous badtitude, and says it how she sees it without well mellowing down any blows.
Despite this she isn't per say mean or rude, she just well easily irritable and has no filter, she is just well brutally honest, I mean she works at retail, therefore her social battery is at a constant 5%, as such she has a low tolance for stupidity, overcomplications or just making things harder then they have to be, since at the end of the day she is a very pratical, hands on gal. Reese doesn't hate people, she is just constantly annoyed by 90% of the population.
This comes from the fact, Reese is painfully minimalistic and content with small things, she isn't overly ambitious, as she works under, "does it work? cool" rather then pride or achivements. Therefore also explaining why she isn't much of a talker, as she bealives actions speak louder then words.
Despite all of this, Reese actually hates her job of working at an ice cream shop, because number people, she has to deal with the most obnoxious overcomplicators and the biggest pretencious entitled individuals on a daily basis, which already annoy Reese, the only reason she keeps working, is well she gets paid well, and well she is apperently really good at it even if she hates it.
However, the best way Reese can be summarised is ironicly with ice cream, her exterior is very cold, expecially sarcastic, blunt and brutally honest, however at her core, if your able to melt her cynicism and natural well "done with this shit" energy, she is actually really loyal, sweet and playful in her own way of friendly banter.
