I heard a story about a Rabbi visiting a country named Tridia. They had some strange customs, one of which was an audience with the King where the Trids would lean over after being greeted by the King and then he would kick them in the butt. The Rabbi says to himself, "Well, when in Rome..." So he leaned over too, after beind greeted.
The King said, "Silly Rabbi, kicks are for Trids."
