England's West Country is known for its charming cottage-like shops. While visiting the area, my friend peered in through one window to see shelf upon shelf of interesting looking books. So, she went inside.
A woman appeared through a beaded curtain and asked,
"Can I help you?"
"No, just browsing," said my friend.
"Fine," came the reply. "But, just so you know, around here, most people knock before entering someone's home."
