The Ultimate Guide to Tipping Etiquette

How much of a tip should one leave? Yeah, 10 to 15 percent of the pretax total of your bill, we know that. But can this percentage decrease or increase depending on the circumstances of the dinner? It sure can! And here's how.

Here's a comprehensive guide to tipping at cafes, restaurants, bars, gelaterias, bistros, teahouses, and other eating establishments of all countries and continents!
