What is a common indicator of potential fraud that a teller should watch for?

Unusual customer behavior is a key indicator of potential fraud that a bank teller should be vigilant about. This can encompass a range of suspicious activities, such as a customer acting excessively nervous, avoiding eye contact, making inconsistent statements, or exhibiting unfamiliarity with standard banking processes. Such behaviors may suggest that the individual is trying to conceal fraudulent intentions or is involved in deceptive practices.

In the context of banking, observing these signs allows tellers to take proactive measures, such as asking additional questions or requiring verification before processing certain transactions. Recognizing unusual behavior provides an opportunity for tellers to prevent fraud before it occurs, thereby protecting both the bank and its customers.
