Wonder how much to tip in restaurants? This survey will help

When you eat out at restaurants while holidaying around the world, there is always a nagging question after you have your food: how much to tip the restaurant staff.
A new research from Good Housekeeping Institute helps tourists to exactly know how much they must offer as a tip while dining out in different parts of the world.
In most Western countries tipping is customary, but tourists risk offending staff if they offer money after a meal in some parts of the world - including China and Japan, MailOnline reports quoting the Good Housekeeping Institute study.
The research reveals where in the world are you expected to tip, and how much is an acceptable amount to leave.
Sara Benwell, Consumer Editor at Good Housekeeping, said:
    "In Japan, there is a no-tipping culture, and you may offend your waiter if you try to give him some money, while in America, tips are very much expected, and it's rude if you don't leave anything. In France, the service charge must be included in the bill by law. However, many locals will also leave some coins as an extra sign of appreciation."
Even though the survey doesn't mention the tipping habits at Dubai restaurants, diners tend to offer tip as a token for good service here.
