How Much Should You Tip?
There is no national tipping standard; state, city and service type all matter. Check the bill for a service charge, then tip on the pre-tax amount. Dine-in is often 15 to 20 percent, delivery 10 to 15, and counter service can be lower.
Common ranges
Dine-in: 15 to 20 percent, up to 25 for excellent service. Delivery: 10 to 15. Taxi/rideshare: 10 to 15. Hotel housekeeping: 2 to 5 dollars per night.
These are norms, not legal requirements; a tip is not mandatory unless the bill states a service charge.
Service-charge traps
Some restaurants add an 18 to 20 percent service charge and then default the card terminal to another 20 percent tip, which double-charges you.
Read the receipt and terminal; if a service charge is already there, ask whether it reaches the staff.
FAQ
Should I tip for bad service?
You can tip less, but separate server issues from kitchen or wait-time issues.
Is a 25 percent default normal?
It is uncommon; choose custom or skip and enter the percentage you want.
