How Much Should You Tip?
Tipping norms vary by service type. Here's a general guide:

| Sit-down restaurant | 18–20% | 25%+ |
| Buffet | 10% | 15% |
| Bartender | $1–2 per drink | 20%, or $2+ per drink |
| Food delivery | 15–20% | 25% |

How to Calculate a Tip
The formula is simple:
Tip Amount = Bill × (Tip % ÷ 100)
Total = Bill + Tip Amount
Per Person = Total ÷ Number of People
For example, a $80 dinner bill with a 20% tip: $80 × 0.20 = $16 tip, making the total $96. Split four ways, each person pays $24.
Should You Tip on the Pre-Tax or Post-Tax Amount?
Technically, tipping on the pre-tax amount is the most common standard — the server didn't provide the government's portion of your bill. That said, the difference on a typical meal is small (a dollar or two), and most people tip on the post-tax total for simplicity.
