Understanding Tipping Culture
Why We Tip
In the US, tipping is a major part of service worker income. Federal minimum wage for tipped workers is just $2.13/hour, meaning tips make up the difference to $7.25+/hour.
Tip Percentages
- 10%: Poor service, minimum acknowledgment
- 15%: Adequate service, acceptable
- 18%: Good service, standard in many restaurants
- 20%: Great service, above expectations
- 25%: Exceptional service, outstanding
When NOT to Tip
Avoid tipping in establishments where service charge is included (some restaurants, tours). Also not expected for fast food, self-service, or when service is genuinely terrible.
