|Self-checkout machines asking customers to tip
Tipping in restaurants and hotels is normal in many countries. People put tips in a jar near a cash register. There is now a new way to tip – self checkout machines. People are not happy about them because they are asking for a tip. They are in bookstores and clothes shops in the USA. There is no face-to-face contact between people, so customers in stores are unhappy about tipping a machine.
