Anthony Rudolf, general manager at Thomas Keller's Per Se, spoke at the TEDxEast conference recently on the topic of chivalry. His isn't the sort that involves bygone eras and knights (though his boss did recently receive the French Legion of Honor). Rudolf says the idea of a code of honorable practices is very much alive, and taught in the dining rooms of certain restaurants.
In a dining room, according to Rudolf, "you're taught to open doors, to pull out chairs," and other courtesies. "The right restaurant doesn't make you a good waiter or waitress, it makes you a good person, that above all, put others' needs first." Here's Rudolf's full speech, where he lays out his "code of hospitality."
