According to a recent survey by the Living Social and Mandala Research organization, Americans are the planet's worst tourists. More than 5,000 people were asked, most of them Americans pointing accusing fingers at themselves.

Other voters: Irish people said British were the worst. The British, in turn, named the Germans. Everyone agreed that Chinese tourists are the most polite, except when they gather in casinos, where their gambling fascination makes them behave like Americans.
