Two decades ago I went into a restaurant in San Diego with my family and my wife's mom and ordered SOS. The lady brought me a huge plateful and smiled when she set it in front of me. I looked up and recognized her as a sailor who had worked in engineering supply when I was at Seal Beach. She wasn't the one who had taken our order, but was the head night chef in the place, and had seen me when she looked out to see who had ordered her "specialty".
"Eat up, Gunny. There's more where that came from".
It was delicious and I wasn't charged for it, just the drink and desert.
I still make it at home every once in a while. I actually like it if it's done right.
