Final answer:
ATM withdrawal limits usually apply to both ATM and in-branch transactions to ensure security and control, but branch staff may override these limits under certain bank policies or circumstances.
Step-by-step explanation:
If the ATM is down and an authorized express CUCARD user goes into a branch, the ATM limits typically still apply because these limits are set to help maintain security and budgetary control measures.
In a branch scenario, the staff can verify the identity of the cardholder and provide access to funds beyond the ATM limit if bank policies permit. It's important to remember that individual bank policies may vary, and there could be exceptions based on the specific circumstances or customer profiles.
