DEAR MISS MANNERS: What is the proper way to eat potato chips?

GENTLE READER: With a knife and fork. A fruit knife and an oyster fork, to be specific. Good heavens, what is the world coming to? Miss Manners does not mind explaining the finer points of gracious living, but she feels that anyone without the sense to pick up a potato chip and stuff it in their face should probably not be running around loose on the streets.

Judith Martin (b. 1938) American author, journalist, etiquette expert [a.k.a. Miss Manners]
