beware of the buffet

"In a 1922 housekeeping book entitled How to Prepare and Serve a Meal, Lillian B. Lansdown wrote:
The concept of eating a buffet arose in mid 17th century France, when gentleman callers would arrive at the homes of ladies they wanted to woo unexpectedly. Their surprise arrival would throw the kitchen staff in to a panic and the only food that could be served was a selection of what was found in the cold room.
The informal luncheon or lunch—originally the light meal eaten between breakfast and dinner, but now often taking the place of dinner, the fashionable hour being one (or half after if cards are to follow) —is of two kinds. The "buffet" luncheon, at which the guests eat standing; and the luncheon served at small tables, at which the guests are seated....
The knife is tabooed at the “buffet” lunch, hence all the food must be such as can be eaten with fork or spoon. As a rule, friends of the hostess serve... The following dishes cover the essentials of a “buffet” luncheon. Beverages: punch, coffee, chocolate (poured from urn, or filled cups brought from pantry on tray); hot entrées of various sorts (served from chafing dish or platter) preceded by hot bouillon; cold entrées, salads, lobster, potatoes, chicken, shrimp, with heavy dressings; hot rolls, wafer-cut sandwiches (lettuce, tomato, deviled ham, etc.); small cakes, frozen creams and ices.
The informal luncheon at small tables calls for service by a number of maids, hence the “buffet” plan is preferable.

The "all-you-can-eat" buffet has been ascribed to Herb Macdonald, a hotel manager in Minneapolis, Minnesota who introduced the idea in 1946. In his 1965 novel The Muses of Ruin, William Pearson wrote, of the buffet:
At midnight every self-respecting casino premières its buffet—the eighth wonder of the world, the one true art form this androgynous harlot of cities has delivered herself of.... We marvel at the Great Pyramids, but they were built over decades; the midnight buffet is built daily. Crushed-ice castles and grottoes chill the shrimp and lobster. Sculptured aspic is scrolled with Paisley arabesques. They are, laid out with reverent artistry: hors d'oeuvres, relish, salads, and sauces; crab, herring oyster, sturgeon, octopus, and salmon; turkey, ham, roast beef, casseroles, fondues, and curries; cheeses, fruits and pastries. How many times you go through the line is a private matter between you and your capacity, and then between your capacity and the chef's evil eye."
