Everybody knows what a bank is all about. Bank is an Organization or corporation or financial intermediary that provides financial services and conducting current accounts for his or her customer. "The bank undertakes to receive money and to collect bills for its customer's account. The proceeds so received are not to be held in trust for the customer, but the bank borrows the proceeds and undertakes to repay them. The promise to repay is to repay at the branch of the bank where the account is kept,during banking hours. It includes a promise to repay any part of the amount due against the written order of the customer addressed to the bank at the branch. Bankers never do make a payment to a customer in respect of a current account except upon demand."
