If you're not in the account, DON'T TALK

Today i had a very old lady come in to the bank where i work. She came in with another woman (i'm guessing daughter).I start talking to the customer. And she answered just fine. She understood what i was saying. The stupid woman said "SHE WANTS TO DO A WITHDRAWAL OF $---.. And i asked the customer if that's what she wanted to do to confirm she understood that we were going to take money our of her acct. Also because of financial elder abuse. All of a sudden, the stupid woman said " YOU GOTTA TALK TO ME!" so i give her the same attitude back, and i made it CLEAR to her. " It's HER acct so i gotta talk to HER!" That shut her up. But then, she told the customer, "i gotta add my name to your account so i don't have to go through this" When i finished the transaction, the stupid woman asked me, what's the balance in her savings? Is it ---? (and it WAS the amount she said)" 🙄🙄😒😒😒 but i just told her.. I CAN'T DISCLOSE THAT. in my mind though I'm like.. WOMAN... WHAT PART OF YOU DON'T HAVE RIGHTS TO ANY OF HER ACCOUNTS AND THE INFO DON'T YOU UNDERSTAND?.. then the stupid woman told the customer "Mama, ask her how much you have in your savings" 🙄🙄🙄😒😒😒....ughhh... I ended up giving them the balance because my customer asked... But these ppl need to learn when to shut the hell up...
