About this certification
The check arrives. Someone says "let's just split it evenly." The person who had a side salad goes quiet. This program prepares you for that moment. It sets out the recognised fairness models, the correct way to handle tax and tip, and the etiquette that keeps the table friendly once the money's been sorted.
Graduates can produce a fair itemised split in under two minutes, spot an included gratuity before anyone tips twice, and apply proportional splitting to shared households with confidence and tact.

- The three fairness models (even, itemised, and hybrid) and when each one applies
- Tipping on the pre-tax subtotal, and sharing tax in proportion
