听力原文： And the last stop on our tour is the cafeteria. The cafeteria is open in the morning from seven to ten and for lunch from twelve noon to two-thirty. Hot food is served from this area on the right; sandwiches and snacks are over there on the left; and in the middle, here, is the salad bar. In your employee orientation pack you'll find a cafe card. This first one is complimentary. It has ten euros worth of credit on it. When you've selected your food, take it to the checkout. The cashier will add up your purchases and tell you how much credit you have left. When it is used up, you can purchase a new card. There's a card machine in the lobby. Let's all get a cup of coffee and sit here in the cafeteria where I'll try to answer any questions you have.
