Helpful Hints dated December 8, 2014:
"Tipping: You may think that the restaurants are somewhat expensive but, unlike the USA, restaurant menu prices INCLUDE service but not tip.
If your meal is exceptional, it is nice to leave an additional tip (up to 10%).
The villa, hotel or apartment maid should be tipped a minimum of $10 per bedroom per day.
The person greeting you at the airport and assisting with your bags should also be tipped (minimum of $20 per couple).
If you have asked for other services such as a massage, a baby-sitter, boat charter, private chef, etc., a tip is always appreciated and should be
determined by the level of service received.

Personally, I usually leave 10 Euros a day.
