Working as a Window clerk at Star Assistance for almost five years I am working here . I love exploring new things and playing games . Recently I heard about a new exchange betting id that was suggested by my friend . A window clerk is responsible for performing various tasks in a post office, like receiving letters and parcels, selling revenue postage stamps, and examining mail for correct postage related tasks. A window clerk is also expected to help customers with shipments. They may also distribute post office packages and mail. This job requires a diploma.
