Bank Teller

A bank employee whose job it is to receive deposits from customers, and to facilitate withdrawals. Generally, they are found behind a counter, often with some sort of fence or window to help protect them from direct assault, and often wearing the same translucent green cap that accountants and card sharks wear. For many bank customers, this is the only employee they will see on a regular basis.

In the Situation Comedy, the Bank Teller is generally an Obstructive Bureaucrat, who makes the simplest transaction into an exercise in negotiation, resulting in long lines. Often punctuated by closing the window just as the protagonist finally gets to the front of the line.

In more dramatic fiction, such as The Western, the bank teller's primary function is appearing in a Bank Robbery plotline. They will be threatened by the robbers, sometimes killed, and may be taken hostage. (Especially if young, female and at least moderately attractive.)

More rarely, but especially in the mystery genre, a bank teller may commit or be accused of committing embezzlement.

In the 21st Century, the use of automatic teller machines, credit cards and Internet banking have made the bank teller less visible, but no less important to a bank's image.

Examples of Bank Teller include:
