What is Automatic Gratuity?
Automatic gratuity is a fixed service charge, typically 18%, added by the restaurant for large groups of six or more. If this charge is present on the bill, an additional tip is not required.
Supporting Details:
- Check the receipt for terms like "service fee" or "auto-grat".
- It replaces the need for voluntary tipping.
- Applies to the pre-tax subtotal of the meal.
