Once again , I'm astounded , what a guy can learn on the Forum. WOW! There's a story in an old book I read. A young , "over- the- mountain boy " was sent East , by his father , to attend a school to be taught reading , writing , and other school studies not available on the frontier of western Appalachia. The travelers came to an inn on the eastern side of the mountains , and sat down to eat supper. The young boy sat at a long dinner table , with the rest of the guests. The food he was given was very tasty , but the dark colored drink he was supplied with , to wash the food down , was to him , unpalatable , and too strong to drink. To his dismay , soon as he drank the liquid from the small cup , someone came and filled the cup again . He was taught back woods table manners , that required him to eat and drink , what he was given , w/o complaint. Finally , the fellow sitting beside him was finished eating , and turned his empty cup upside down , so it couldn't be filled. At last , our back woods youngster , learned how to stop the foul liquid from automatically , going into his cup. Just turn the cup upside down before the meal , and the foul tasting , "coffee" wouldn't be dispensed. ............Can't remember the date of this story , so I'll have to reread some books in my collection. Could have been around 1800.
