Salesmanship in a store as large as Macy's must of necessity include the knowledge of considerable detail in the making out of sales slips, procedure with regard to C. O. D. deliveries, depositors' accounts, exchanges and the like. This knowledge is a fundamental part of each salesperson's equipment. His or her efficiency must come, however, from a far wider development of the possibilities of the salesmanship, from the "playing of the game," as the department manager put it but a moment ago--the understanding use of courtesy, merchandise knowledge, helpfulness. Such efficiency pays. The Macy folk who come to use it regularly soon find themselves advancing to responsible and highly-paid positions. It is interesting to follow the career of a sales slip from the time it is made out--when the sale is made--until the time that it ceases to function. Here is one of the most important items in the mechanism of a large retail store. It is an essential unit of a carefully developed system to keep track of sales, from the minute that they are made until they are finally delivered and audited. The sales slip--the Macy clerk has three different ones of them in all--is made in three distinct parts--original, duplicate and triplicate. Each of these is divided into several parts; each of which in turn is destined for separate hands. The packer of the merchandise gets one part, which eventually goes to the customer, a second to the cashier, the third the clerk retains. Eventually these last two come together once again in the auditing department and are checked, the one against the other; after which one goes into the archives of the bureau of investigation, in case that there is any further question about the details of the transaction. This one example of the infinite detail in the conduct of a great store is a slight indication of the responsibility upon the shoulders of not only its managers but the rank and file of its salesforce as well. A single error in the making out of a sales slip may easily result in expensive and harassing complications all the way along the line. A system of transfer books enables the store's customer to make purchases in its various departments with the least possible waiting. The goods and prices are entered in a small book which is given the customer at the time of the first purchase of the day. While the customer is making his or her other purchases they are being sent to the wrapping room where they are held in a growing group until the customer presents the book to the cashier at the transfer desk on the main floor, pays the total and, a few minutes later, receives a neat package in which all of the items are wrapped together; or else it is sent to any designated address.
