Montelongo was the manager of the biggest bank of Isthmus, Banco de Isthmus. When Bond came to take a small deposit in the bank, he told his people downstairs capable to do it. But when Bond put his briefcase full of money on his desk, he became friendly. After he counted the money he established a line of credit for Bond at the casino. Few days later Bond came again with his briefcase and he made a withdrawal. Montelongo was so dissapointed.
