The customer is requesting the bank manager to open a "Real Current Account" where the funds deposited cannot be used by the bank for investments. In the current account, the customer's funds are likely being used by the bank for earning profits daily according to the account terms. The customer wants the bank to only charge maintenance fees and act as a custodian for the deposited assets rather than using them. Additionally, the customer notes that opening real current accounts could benefit the bank's survival by avoiding a situation where all customers withdraw deposits at the same time.
