The general understanding existing with Department Stores concerning merchandise sold is, that if for any reason it is not satisfactory it may be returned and exchanged or money refunded, on customer's request. This understanding, however, has some qualifications,—such as articles that have been worn, when such a time has elapsed between the purchase and return as to render articles unsalable, goods made to order according to measurements, toilet goods, etc.; but, with few exceptions, the almost unalterable rule is to exchange cheerfully, to avoid unnecessary questions or remarks, rather preferring to be occasionally the subject of imposition than to leave an unpleasant impression. Where an exchange is desired in the same department as purchase was originally made, an exchange bill is issued. Should the customer select other goods of less value than the exchange bill, the cash office, when new check and exchange bill are received, will return the difference in change. The exchange bill, when signed by the head of a department, or one authorized, is good for its value in any department; and should the customer not be able to make a suitable selection, this bill, when properly stamped or signed, is good for cash on presentation. These exchanges, as collected and audited, are usually deducted from each department's daily sales.
