Man: One more thing, how much would the fares cost?
Woman:  Well, the bus is $1.8 in cash and the train is $10 each way. But, do you have a Travel Link Card?
Man: No, but I may get one before tomorrow.
Woman:  Alright, if you have the card, you can pay considerably less. The bus will cost you $1.5 and the train to Harbour... sorry, wait, it will still cost you $10 because it is during rush hour in the morning, I’m afraid. Yet, if you could return at an off-peak time...
Man: What do you mean by that?
Woman:  All right, if you could begin your returning journey before 5 in the afternoon or later than 7:45 (a quarter to eight) in the evening... Man: In fact, my plan is that I won’t start to go back home until 8 o’clock anyway.
Woman:  Then you can save a lot of cash using your Travel Link Card. You did mention that you were planning to buy one, didn’t you?
Man: Yes, today, maybe later, I’ll pick one up.
Woman:  It means, with cash, it would cost you $10, but if with your card, you will only pay $7.15 for returning.
Man: Thank you.
Woman:  Is there anything else I can help you with?
Man: Ah, yes. In fact, I would like to know if the Travel Link Card
supports ferry services?
Woman:  If the ferry services is Harbour City ferries that connect the northern and southern banks, then yes. They are commuter ferries, a one-way trip costs $4.5, but with the Travel Link Card you will enjoy a 20% discount, and the cost will be $3.55.
Man: So, $3.55 for it... What about the tour boats?
Woman:  You mean those ferries going upriver on sightseeing tours for tourists? No, they do not belong to the Travel Link company, and they only take cash and credit card.
Man: Oh, I see. So, I may believe that you might not know how much they cost for one tour?
Woman:  Actually, I do know. I took a friend to the trip up river just last week. We decided to go an afternoon tour and it cost us $35 each. There is also a whole-day option costing $65.
Man: Thank you. You really helped me a lot.
Woman:  With pleasure. Do enjoy your trip!
