Latin America – Tipping customs vary widely, from 8 to 10 percent included in the bill in Brazilian and Chilean restaurants, to leaving 10-15 percent in Mexican ones.

Asia – The only tipping that applies universally is to always give the bellman at least $1 per bag. Restaurant tipping varies widely, from absolutely no tipping in China to $1 per diner in Thailand to 10 percent of the bill in Singapore and Malaysia.

Europe – 10 percent is standard for meals in Great Britain and Italy, up to 15 percent in Germany, and in Scandinavia, either the tip is included as a service charge or no tipping is done.

Middle East – It becomes a bit easier here as Dubai, Egypt, Jordan, and Israel all have a set percentage added to restaurant bills.
