How do I calculate a 20% tip quickly?

Move the decimal one place left (this is 10%), then double it. For a $45.00 bill: 10% = $4.50, doubled = $9.00 tip. For 15%, find 10% and add half: $4.50 + $2.25 = $6.75. These mental shortcuts make tipping easy.

Should I tip on the total bill including tax?

Technically, you should tip on the pre-tax amount. However, tipping on the total is common and slightly more generous. For large bills, the difference matters more. Either approach is acceptable - generosity is appreciated.

How much should I tip for delivery?

15-20% is standard for food delivery, with a $5 minimum for short distances. Consider tipping more for long distances, bad weather, heavy/large orders, or apartment deliveries requiring stairs. Delivery drivers use their own vehicles and gas.

Do I tip on takeout orders?

Tipping on takeout is optional but appreciated, typically 10% or a few dollars. During busy times or for complex orders, tipping acknowledges the extra work. Some argue takeout does not warrant tips since there is no table service.

How should I split the bill with friends?

The easiest method is dividing the total (including tip) equally. For fairness when orders vary significantly, each person can calculate their share plus tip. Apps like Splitwise help track who owes what for recurring group expenses.
