①Nowadays，we can see more and more robot waiters in restaurants around the world.They can welcome people and take with them to their tables.They can also send food and drinks and bring dirty dishes back to the kitchen.Some have cat﹣like faces and even make noises when you touch their heads.But are robots waiters the future？It is a question the restaurant industry is trying to answer.
②Robot waiters are useful.One reason is that the sales of robots have been growing in recent years.There are tens of thousands of them now moving through eating places around the world.
③"I'm sure this is where the world is going."said Denis Reynolds，head of the Hilton College of Global Hospitality.I cadership at the University of Houston.The school's restaurant began using robot waiters in December.2022.The students and teachers love robot waiters very much.They have cut down the work of humans and improved service.
④But others say robot waiters still have a long way to go before they can serve others like humans.They cannot take orders and many restaurants have steps，outdoor patios（露台）and other physical challenges they can't get used to.Besides，restaurants are noisy places.They are crowded with people.So these robot waiters can easily hit people.
⑤"Restaurants are pretty chaotic（无秩序的）places，so it's very hard to use a robot，"said Craig Le Clair from the advising company Forrester.
