Here tipping is mostly optional and for showing good etiquette.
Egypt – Here the mommas did good raising their kids: 10% is considered having good manners. The more you tip, the better your manners. So therefore, it is expected to show good manners next time you rope-walk across the pyramids for the family photo.
Kenya – About 10% is considered friendly. Tipping your housekeeper will ensure good service and motivation. Who wants broken china glass anyway? Also, tipping your safari guide? Encourages smiling faces and less animals in your tour truck. Custom is 10 dollars per day, and your tracker 5 dollars per day, but only at the end of the safari.
Nigeria – Tipping here is optional. Fun fact: Do not use your left hand for anything. It is considered unclean. So, inevitable question: What about the left-handed ones?
Republic of the Congo – Tipping here is 10%. Waving at or calling server’s names is very impolite (it is in the U.S., too, but people still do it, right?) . You may raise your hand or make eye contact.
South Africa – Tipping here is common. 10-15% is expected in restaurants and bars.
Tanzania – Tipping is not expected, but appreciated. Also home of the Akemi Revolving Restaurant. Check it out:
