The United States is leading in the countries that tip category, every single time. Tipping is called a gratuity here, where servers or those in customer service ask for a thank you in the form of money. Standard tip amounts range from 15 to 20 percent. You might see it added to your bill in a restaurant, a tip jar at a donut shop, or you may be invited by your conscience to leave one when you are served food or drink by a stranger. Most in the service industry are paid less as they rely on tips as a large source of their income. Follow your instinct here, Americans have a long memory when it comes to those who don't tip.
Canadians are renowned in the world for their polite manners and nice smiles, and you will usually see this reflected in their customer service. Their mindset behind tipping is very similar to America, with a standard tip range from 15 to 20 percent being acceptable. It might be added to your bill in some locations, or you may want to simply follow the country's mindset of offering money as a token of gratuity for service that usually is paid at the rate of minimum wage. This is the case in most countries that tip.
Canadians also typically don't like it and find it inappropriate when they are asked if they want change from a bill. They will decide if and how much they tip. Follow suit. Don't tip too little if you tip. If you don't have enough, don't tip. Pennies or a dollar or two on a $100 bill will be considered an offense that Canadians will not smile over.
Belgium is a little different in Canada in that they do have a "keep the change" policy. That is their standard of tipping, and you might see a bill rounded up to the next dollar value. You can leave that as your tip, or add more if you have found your service experience particularly enlightening.
In Brazil, a tip is a standard practice as it is in America and Canada. It's expected. When you go out, have enough for the meal and the tip. Brazil standards are around the 10 percent mark. What makes this country a little easier to budget for is that their menu prices will already reflect the cost of sales tax. That may make it easier for you to budget your tip. In other countries that tip, customers will tip 15 to 20 percent on the pre-sales total. In Brazil, it is up to you if you want to go above the 10 percent rate.
The Caribbean is a common place for North Americans to travel as it is often short in travel time and an easy getaway to a location with an ideal climate. The Caribbean is also home to a number of countries that tip and expect tipping in return. The local mindset is very service oriented due to the number of tourists this region sees annually. Often a 10 to 15 percent charge is added to your bill in a restaurant and hotel. Anything additional is up to you, but good tipping will be remembered and rewarded with exceptional service for the entirety of your stay while you are visiting in this region.
Of all the countries in the world, the United States tips the most, but other countries that tip include Canada, Belgium, Brazil, and the Caribbean.
