From Vault13 Studios:
The International Tip Calculator automatically calculates tips and provides useful tipping information for over 100 countries spanning the globe. Never be unsure of how much to tip waiters, taxi drivers, porters and maids again. Great anywhere for quickly calculating tips and splitting bills. Simply choose a destination, enter an amount and your tip is calculated. Use its rounding feature to round your total to the nearest whole currency; a custom in many countries and a convenient method to simplify bill paying. Fill in the local tax rate for a more accurate tip. The International Tip Calculator takes the guess work out of tipping at home and around the world.
