How much should you tip?
In many U.S. full-service restaurants, 18–20% is a common reference point, but customary tipping varies by setting, region, and service. Consider what is already included in the receipt.
Tip before or after tax?

Check for service charges
Some establishments add an automatic service charge or gratuity. Review the bill to avoid mistakenly adding another percentage when you didn’t intend to.
