When San Francisco etiquette coach Lisa Grotts travels, she abides by the John Steinbeck quote "A journey is like a marriage. The certain way to be wrong is to think you can control it." While on a radio media tour a few years back, Grotts spent so much time in major airports, she began to notice a plethora of travel faux pas, "luggage carts crashing into the shins of others; angry, unhappy passengers; passengers in coach placing their luggage in first, etc. I wrote my first chapter [of the guide] that week!" she says. In November, her compilation of all her travel knowledge, "A Traveler's Passport to Etiquette" hit the shelves.
