One of the main factors of the job is diligence. Be productive, be on time, make sure that the inventory has been straightened out so that the connection to the warehouse to the store will not be overrun by overstock. If the numbers are closer to being correct, the happier the customers will be. Keep the employees from stalling, make sure they know their tasks and finish up shipments as quickly as possible, or treat the customers with the utmost respect. Keeps things organized and controlled so that the employee can find the items quickly without issue. Other than that, be kind to the customer and make sure they are in and out of the store.
