My friend John has got a restaurant in a big city. It is near a supermarket. He gets ten robots for the restaurant. Each robot costs (价钱为) 20,000 yuan. The restaurant is not big, but very popular. Now more and more people come here for dinner.

The robots have different jobs in the restaurant. Two robots cook different kinds of food; one washes the dishes; one cleans the floor and the others give food to the guests (客人).
