Explanation
In India, tipping at restaurants is considered a polite gesture for good service, but it is not mandatory or deeply ingrained in the culture. Many middle-class and budget restaurants include a service charge (often 5-10%) on the bill, which reduces the expectation of an additional tip. However, in upscale or tourist-oriented restaurants, leaving 10-15% of the bill as a tip is common and appreciated.
Local Tip
If no service charge is added, leave 10% of the bill in cash or round up the amount as a tip.
How it compares elsewhere
Tipping is considered insulting as it implies the staff needs extra money; excellent service is the norm.
Tipping 15-20% is mandatory and expected for service staff, as they rely on tips for income.
A service charge is included in the bill (service compris), so additional tipping is optional but rounding up is polite.
