M: Hello. Grayson’s Adventure Days. How can I help you?
W: Oh, good morning. I want to book an activity day as a birthday present for my father, so could you give me an idea of the sorts of things you organise?
M: What a great present! Do you want the activity to take place in a particular location?
W: No, anywhere in the country would be OK.
M: Right. Well, how about bungee jumping? That’s our most popular activity.
W: Uh-huh?
M: After a safety briefing, you’re securely fastened to the correct bungee rope for your weight. Then the crane takes you up to a height of 50 metres in a cage, and you jump from it.
W: You make it sound so easy!
M: In fact, some people change their minds at the last moment. But for the really brave, you can also book our special, which is one normal bungee jump and then a backwards one. It’s quite an experience!
W: I can imagine! Is it available every day?
M: We do bungee jumping all year round, on over 120 days, and in various locations,[13]but you should try to book about four weeks in advance, if possible, as it’s very popular.
W: OK. And are there any age restrictions? It’ll be my father’s fiftieth birthday, so I hope he isn’t too old.
M: No, he certainly isn’t too old, but we’ll require a certificate from a doctor, to confirm that he’s in good health.
W: Oh, he’s very fit, so that won’t be a problem. How much is it?
M:[15]It costs ￡57 per person for the standard jump, and ￡97 for the special.
W: OK, I’ll get back to you in the next few days. Thanks very much for your help.
M: No problem. Bye.
W: Bye.
