This tourist's guide to tipping is a colorful and heavily detailed run-through of what travelers should keep in mind when wanting to stay polite while on the road.
From taxi drivers to bartenders, all sorts of services are included in the chart, and readers can gauge how to appropriately show their appreciation to a variety of staff. Because tipping is a tendency that ranges widely from region to region, a go-to chart like this is a necessary and welcomed piece. The guide points out critical information, including not only where to tip but how much to tip depending on where you are and what services you're paying for.
The specificity of this data visualization piece is where it really shines, coming in handy the same way a travel book might.
