[Q]: W: Yes, I'd like to go on a sailing holiday this summer in Italy. M: Have you been sailing before? W: No. I wanted to go to Sweden last year, but I didn't have enough money. M: Well, it is quite expensive. Sailing holidays start at about three hundred pounds. W: Yes, my friends went in August last year. They paid four hundred and fifty pounds each. The most I can pay is three hundred and eighty pounds. M: Well, that should be enough. Would you like to be by the sea or a lake? W: Well, I'd prefer a lake in the mountains. M: Okay. The Aqua Center in north Italy will be best for you. That costs 370. W: Okay. Can I pay by credit card? I haven't got my checkbook. M: Yes, that's fine. What was said before this conversation?
