Harold Sure walked into Octopus National Bank and made a presentment of a $12,000 check drawn on the bank to the head cashier, Christopher Coin, who was staffing one of the teller's windows. Coin asked p. 755Sure (who was the check's payee) to indorse the check on the back and then tapped the computer's memory bank to check on the state of the drawer's account. The computer replied that the account contained "one thousand dollars," but Coin misread the display and thought it said "one hundred thousand dollars." He went back to the teller's window and counted out the money thoughtfully. When he was done, a nagging doubt about his vision overcame him, andpassing the money to Surehe said, "Excuse me a minute," and rechecked the computer. This time he read the amount correctly and rushed back to his window to discover Sure still standing there, slowly recounting the money in front of him. Coin snatched the money out of Sure's hands, saying, "I'm sorry, we must dishonor the check." Sure protested, but in vain. If Sure sues, will he win? Had the bank made final payment? See 4-215(a)(1)
