Paul D. Bunker, Post Exchange Methods
“ In all cases of such sales, the clerk simply gives the customer his goods, receiving the money therefor, makes change if necessary, rings up the amount of the sale on the cash register and places the cash therein. The most important part of this transaction, insofar as our system is concerned, is described in the next-to-last clause. If the salesman once rings up the correct amount on the cash register, the store is sure that the transaction is closed, and closed properly. ”
