Why must Window Clerks be knowledgeable about postal pricing?

Window Clerks must be knowledgeable about postal pricing primarily to provide accurate customer information. When customers come to the postal counter, they rely on clerks to guide them in selecting the right mailing options based on their needs and budget. Understanding various pricing structures—including first class, priority, and express mail rates—allows clerks to make appropriate recommendations, ensuring customers pay the correct amount for their services.

This knowledge not only facilitates reliable transactions but also enhances customer satisfaction. Being well-informed about current rates and any applicable discounts enables clerks to assist customers in making informed decisions, thus promoting a smoother and more efficient service experience.
