"Again She Orders – 'A Chicken Salad, Please'" is a 1921 advertisement for the two-volume Book of Etiquette.
[1] One of her first assignments was to write an advertisement selling the remaining copies of the pre-1900 Encyclopedia of Etiquette by Eleanor Holt.
[3] The advertisement portrayed the plight of a young woman who, on a date with a man she wants to impress, doesn't know how to order dinner in a fancy restaurant, which Victor Schwab said was effective because it "capsulized a common and embarrassing situation".
She hears him repeat the order to the waiter, in a rather surprised tone.
[1][6]: 67 Schwab in 1962 noted that the ad was "so noteworthy and memorable" that the headline was still part of everyday speech.
