The bank thing makes no sense whatsoever, its not like its an ISA or anything its just a current account. Amber's just trying to make it seem like her bank cares for her. (she does this A LOT, vet, doctors, attendants.) Its all about creating the air of self-importance fuck even the work place remember. I have not seen a person who does it so much but it makes sense her family hate her, her "relationship" is utterly soulless. She has to buy her friends, so she crafts this world where everyone cares about her a lot. They don't though its not sad though because at every single point Amber has had the choice to try and redeem herself by trying to better herself /she is incapable because she IS THE CLUSTER B/
People in that cluster never live happy lives sadly.
she did say if there was LV store nearby she'd have her dream bag now- meaning she'd have taken the cash out to buy it. Not sure if there are other ways to pay, money order or check? I'd say change banks but I'm guessing she can't because of a reason that's been brought up too many times.
