Im more concerned with her needing 30k in cash in the modern world, and pretending it was for Easter. Some dirty sht was happening with that money. Im reminded of senator minendez making ducktakes about the cash he received from corruption.
If you as a private citizen were to be stopped or pulled over with that amount in paper, then it would obviously be confiscated for being fishy. There is no reason to keep such a cumbersome amount, when every single vendor in the country accepts Visa or MasterCard.
Something unsavory was happening.
