In Greece, tipping is optional as charges are added to bills, but it’s polite and generous to add a little extra for good service, especially bearing in mind that the waiters and hotel staff are unlikely to see any of the service charge themselves.
As with many European countries, tipping is nonetheless sought in tourist traps but not in outlying areas.
In bars, tipping is not customary amongst the locals so it’s at your discretion, as is giving a little extra to porters and other hotel staff for good service.
Taxi drivers don’t expect tips – but people often round up the fare, up to an amount equivalent to 10 percent.
