How to understand "cash is counted face to face, and it is irresponsible to go out"?

Editor: I am an old resident of Zhuzhou City, Hunan Province, and I often see a disclaimer "notice" in front of the business counters of bank outlets that "cash is counted face to face, and I am not responsible for going out (or writing)". Is this "disclaimer notice" legal? How to understand "face to face"? He is a bank employee, and it is "irresponsible" for him to count the amount of money withdrawn by the customer with a cash counter or manually in front of the customer, or it is "irresponsible" for the bank employee to hand it over to the customer without counting it face to face, and the customer will hand it over to the customer in front of the counter and in front of the bank employee, otherwise it will be regarded as "face to face". Which way can be called "face-to-face counting" in the true sense? In order to be excused. Please give me your advice. Thank you.
