A tip abroad

8. Tipping in Greece
Tipping in hotels, restaurants and for taxis or tours is common but not obligatory in Greece. It’s up to you if you leave a tip, but it helps to have a rough idea of what to leave for good service should you choose to. 
A few coins should suffice in cafes, or 5-10 per cent of the bill in restaurants if they haven’t already rounded it up to include a gratuity. If you want the tip to reach the waiting staff, leave it as cash rather than adding it as part of your card payment.
Round up short taxi rides to the nearest euro or add 5-10% of the bill for longer journeys. And, for guided tours, allow 2-5 euros per person per day if it’s a group tour, or 20 euros each if it’s private.
9. Tipping in Turkey
Tip 5-10% depending on quality of service. Check whether it has been included in the bill; it may not be as a matter of course. 

Tipping in Asia
In many Asian countries, tipping isn’t especially common. But if an area is popular with tourists it’s more likely that tipping will be expected.
1. Tipping in China
Tipping is uncommon in China. You might find that it is expected in areas popular with tourists but could lead to confusion elsewhere. However, tourist industry professionals (such as tour bus drivers/guides) are likely to expect a tip. 
2. Tipping in Hong Kong
Tipping in Hong Kong is more common than in mainland China. Restaurants may add a service charge of 10-15%, and taxi drivers will normally expect a small tip. 
3. Tipping in Japan
Tipping isn’t culturally normal in Japan, as good service is considered something that should be expected. Attempting to tip could lead to, at best, confusion and, at worst, offence. There may be occasions when you encounter someone who works within the tourist industry who won’t turn down a tip, however it’s best avoided.
4. Tipping in Thailand
Tipping is expected in Bangkok. Hotels and bars may add a service charge to the bill but if they don’t, tip 10% or round up to the nearest 20 baht. Outside Bangkok, tipping isn’t expected but rounding up a bill or fare will normally be considered fair.
