Which I guess if you're basing your ideas about business or the luxury industry based on a sloppy viewing of The Devil Wears Prada and a handful of Sex & The City episodes, that kind of behavior might seem realistic, but if you've ever been around people or enjoyed the company of a person then it just comes off as classless and tasteless and pointless as the majority of the episode. Try treating your assistant like this in front of a possible client and see how fucking far it gets you.

Hilda beats it into Manhattan so that she can throw her huge fucking fit for no reason. It goes like this:

Hilda: "You lost Dad!"
Betty: "I know, sorry!"
Hilda: "You lost Dad!"
Betty: "I know, let's go find him."
Hilda: "Or we can stand on this street corner and bitch and fight and cry for no reason, for the rest of our lives."

Betty: "Hey, there's the doctor! Randomly! Does he know where Dad is?"
Doctor: "Two hours ago I did, but he's on the move I bet. He seemed like he went senile off-screen in this episode and thus that would make sense as a source of narrative tension we're keeping secret from the audience in order to show disrespect both to our viewers and to the basic concepts of storytelling. But I wouldn't worry about it, two strange girls I don't know and am not getting paid to deal with, because he just had a QUADRUPLE BYPASS and thus isn't moving SUPER FAST."
Hilda: "It won't matter how slow he's moving, because I am going to stand right here yelling about how much I care about him, instead of actually looking for him, until the sun goes down."

Doctor: "Oh, I forgot to tell you the results of those tests that we completed hours ago. Your dad is fine."
Hilda: "THAT MAKES ME EVEN MORE MAD."
Betty: "Really? That's sort of stupid."
Hilda: "No, Betty. Not this time. You're not getting away with it. It's your fault our mother is dead, it's your fault our father had a heart attack, it's your fault people get sick and die, it's your fault we took him to the doctor and got this wonderful news, and it's your fault that our father is such a fucking douchebag that he wandered out into the city for NO REASON AT ALL."

Justin: "Oh, Grandpa just came home. I thought I would call you on your portable cellular phone and let you know that, although Grandpa thought otherwise for some reason."
Betty: "I'm so sorry that I'm such a terrible person that I let you be in charge of yourself for five seconds."
