The Piggly Wiggly grocery-store chain was founded in Memphis, Tennessee, in 1916; this store opened its doors in the Bank Block on Grandview Avenue in 1927.

Then new, the Bank Block shopping center, with parking behind the shops, provided the newest conveniences to shoppers, such as the "self-service" Piggly Wiggly.

Until founder Clarence Saunders promoted this method of shopping, customers presented their orders to clerks who gathered the goods from the store shelves.

His approach had customers entering through a turnstile and picking out their own items, which were brought to a checkout location.

According to the company, Saunders was coy about the origin of the Piggly Wiggly name.

One story says that, while riding a train, he looked out his window and saw several pigs struggling to get under a fence, which prompted him to think of the rhyme.
