SOS (sauce on the side)

“SOS” is a famous distress signal. In restaurant lingo, “SOS” means “sauce on the side”—that is, sauce on the side of the plate and not directly on top of the food.  “‘S.O.S.’ (sauce on the side)” has been cited in print since at least 1994.

CONSUMED Why Americans Love, Hate, and Fear Food. By Michelle Stacey. 237 pp. New York: Simon & Schuster. $22.
One explanation, and it points to a major flaw in “Consumed,” is that America’s eating habits aren’t as monolithic as Ms. Stacey assumes. Surely the people driving waiters crazy with their demands for steamed artichokes “S.O.S.” (sauce on the side) aren’t the same people driving up McDonald’s sales.

Clearly you have never worked in a restaurant.  Yes, if a customer orders his meal SOS (sauce on the side) and the kitchen goes ahead and puts sauce on it anyway, the server should tell the chef that the dish must be redone.

Phil: The Little Man Who Makes My Life Hell
The other day, Phil barked out “five fish tacos; one New York, rare—no salt, light pepper, sauce on the side and a side of steamed vegetables—two salmon and a chicken Caesar salad.”
“Bullshit,” I say. “Phil didn’t say nothin’ about a New York SOS [sauce on the side].”
