Priya, being the owner of the bookstore, is ultimately in charge of all the operations, including placing orders for new books. Raj, as her assistant, may carry out these tasks under her direction or with her permission, depending on the level of responsibility Priya has delegated to him. Anika, as a customer, does not have any responsibility for the store's operations, including ordering books or deciding which books are displayed prominently. Her role is limited to purchasing items as a patron of the bookstore. Only Priya and potentially Raj, based on the discretion given by Priya, have the authority to make decisions about inventory and book displays. Anika can make suggestions or requests as a customer, but she does not have the ability to make decisions for the store.
