The map works by telling you exactly how much, if, and when you should tip your waiter, taxi driver or hotel staff. Oh, and what’s even better is that it even tells you how to say thank you by way of a snazzy little language tool.
Normally perceived as an ‘American’ only issue, it’s becoming increasingly customary to tip in more and more countries, even if tipping is not the custom and the service is really bad. To give you an idea, Americans are expected to leave between a 15–20% tip whenever they go out.
