Still uncertain if Pinkie tries to turn a new bimboless leaf on a new diner job, or if she wants to spread it by finding a new place to unfold her wings.
Would be interesting to see if she tried to be very serious this time around to not change anything, wanting to focus on her work. But maybe she overhears her work colleagues being jealous of her youth and positive outlook.
It’s most likely the latter, but she would go to the job interview in style nontheless.
