 The Innovation of Grocery Stores Reading Answer

At the very beginning of the 20th century, American grocery stores offered comprehensive services: the customers would ask help from the people behind the counters (called clerks) for the items they liked, and then the clerks would wrap the items up. For the purpose of saving time, customers had to ask delivery boys or go in person to send the lists of what they intended to buy to the stores in advance and then went to pay for the goods later. Generally speaking, these grocery stores sold only one brand for each item. Such early chain stores as A&P stores, although containing full services, were very time-consuming and inefficient for the purchase.
