A lady signs up for a checking account with a bank. She closes the account a year later. A few years after that, she's involved in a car accident, her attorney negotiates a settlement, and then embezzles the funds. Bad times.
She sues the attorney's bank, which she alleges ignored blatant signs that he was a scheming crook. The bank cries "arbitration!" based on her long-since closed checking account agreement from many years prior. Common sense says "puh-leaze," right? Unrelated disputes, unrelated accounts, and the arbitration agreement was signed in connection to a long-since closed account. Ridiculous.
