How to tip in the U.S

I’m very confused about when and how to tip in the States as I’m new here. Let me know…

There are a few situations where tipping is expected, and primarily it is in restaurants. The restaurants in the U.S. don’t add a service charge; hence it is expected from customers that they will leave tips for the servers. Commonly, people leave a tip that is equal to 15% of the total bill for acceptable service, and about 20% for superior service. If the service was unusually poor, then you could leave a smaller tip, about 10%. Some other cultures where tipping is expected are hairdressers, taxi drivers, hotel porters, parking valets, and bartenders. The general rule is to tip approximately 15% of the bill.
