According to this short, some people call the local grocery store a battleground - people who have never heard of, say, the Revolutionary War.
However! There is “a daily battle is being waged in supermarkets all over this country - a battle for the customer’s dollar.” And clerks are “The Front Line” in this instructional video, complete with information on greeting customers, dispensing change, and looking up prices on canned goods. Warning: contains graphic images of cash registers and Campbell’s Soup.
