Explanation
In Brazil, tipping at restaurants is not mandatory but is considered a polite gesture for good service. A 10% service charge (gorjeta) is often included in the bill, but if it is not, leaving 10% is customary. Brazilians generally tip when service is satisfactory, and it is seen as a way to acknowledge the waiter's effort.
Local Tip
Check your bill for the 10% service charge; if it's not included, leave 10% in cash or add it to the card payment.
How it compares elsewhere
Tipping is not practiced and can be seen as insulting, as good service is expected without extra payment.
Tipping 15-20% is standard and expected for restaurant service, as waitstaff rely on tips for income.
A service charge is included in the bill, so additional tipping is optional but small change (5-10%) is appreciated for exceptional service.
