"It's wise to be aware of the tipping customs in each place you visit to avoid uncomfortable situations, ensure a smooth trip and avoid paying too much which is quite often the result. Knowing which countries where you should leave a tip is just as important as knowing which countries not to," Wego Chief Marketing Officer Joachim Holte said.
As a general rule, tips as a sign of appreciation are expected in restaurants in Austria, Brazil, Chile, Ireland, The Netherlands, Russia, South Africa and Turkey, the report by travel search site in the Asia Pacific and Middle East said.
Checking whether there is a service charge added to your bill is also a good way to tell whether a tip is applicable or not, and then you have the choice to leave a small amount on top if the service was particularly impressive.
However, in the UK, tipping for food in restaurants is required, although unexpected as service charges are generally included.

"In Argentina, tipping is illegal, however, waiters often expect to be tipped by foreigners so if you were to tip, discretion is advised. In the US, low wage earners in the service industry are reliant on tipping to balance out their income, yet in Romania, tips are often declined and in Japan, tipping is considered offensive," Holte said.
In general, people are also expected to give a small tip to the porter as he drops off the luggage in the hotel room.
"You're fairly safe if you round up your fare for taxi drivers anywhere you go apart from New Zealand and Chile, where it's not expected at all," the report said.
It further pointed out that tipping traditions are evolving throughout the world as more people travel.
