Don’t forget to tip your server! If you’re American, there's a good chance you already do.  Americans are the second best tippers in the world, behind Germans.

TripAdvisor recently surveyed more than 9,000 travelers in eight countries and found 69% of Germans say they always tip.  That’s compared to 57% of Americans, 53% of Russians, 40% of Brazilians and 39% of French and British.  Italians came in last, at 23%, behind Spanish at 36%.

The survey found that the top reasons Americans tip are: when staff at restaurants or hotels is helpful, friendly or polite.
