Which of theses fees is the biggest problem for customers who need to use their credit card to take money from an ATM?

The biggest problem for customers using their credit card at an ATM is typically the cash advance fee. This fee can be significantly higher than regular transaction fees and is often accompanied by high-interest rates that start accruing immediately. Additionally, ATM operators may charge their own fees, compounding the costs for the customer. Overall, these combined charges can make withdrawing cash with a credit card an expensive option.
