When Is 15% an Appropriate Tip?
Fifteen percent was the standard restaurant tip in the United States for much of the 20th century. While 18–20% has become the new baseline, 15% remains appropriate in a number of situations and is still widely used for specific service types.
At sit-down restaurants, 15% communicates that service was adequate but not particularly impressive. It is the right amount when your server met the basic expectations — took your order correctly, brought food in reasonable time, refilled drinks — but did not go beyond that baseline. Leaving 15% is not an insult, but most servers today consider 18% the minimum that signals genuine satisfaction.
Where 15% Still Makes Sense
- Buffet restaurants: Where servers primarily clear plates and bring drinks, 10–15% is the accepted range.
- Counter service: For quick service where you order at a counter, 15% is generous and appreciated.
- Average restaurant service: When the server did the job adequately but nothing stood out, 15% is honest feedback.
- Hair salons and barbers: 15% sits at the lower end of the accepted 15–20% range for beauty services.
- Food delivery: 15% is a solid delivery tip that covers the service fairly for average orders.
