Piggly Wiggly was actually the first grocery store to introduce "self-serve" shopping. Before that you would give your list to a clerk to fill your order for you.
Yup. A number of ads from this period and even later instructed the shopper to "ask your grocer" for the specific brand advertised. A Kellogg's ad from a few years before this -- I'll have to scan it and post it -- shows a child coming home from the store with the Wrong Brand:
When Johnny comes Marching home again With a common Imitation -
Send Johnny a Marching back again With a note of Explanation -
Then, underneath that, handwritten:
Never send me anything but Kellogg's - the Original Toasted Corn Flakes
