听力原文：W: Good evening, sir! How can I help yon? M: I’ll have a Scotch. W: We have Old Par, Red Labels, Cutty Sark and Queen Ann. Which would you like? M: Give me a Red Labels. W: One Red Labels. How would you like your Scotch, straight or on the rocks? M: With iced water. How much do I owe you? W: The Red Labels is $8 plus 10% service charge. You can hold the bill until you decide to leave if you like. M: Really? In American bars you pay drink by drink as you get it. That's a little trouble but much safer. You see, American 'bars can be very crowded and it's hard to keep an eye on everyone. Besides you can never know what may happen when people drink too much. W: I see. But we've never met with any experience of a guest sneaking out on us without paying his bill or unable to pay his bill or refusing to pay his bill. M: You're been lucky so far. OK, here is $10 and you can keep the tip. W: That's very kind of you, sir. But we don't accept tips here in the bar. M: That's really interesting. In my country bartenders are paid a much lower basic hourly pay than people in non- tipping positions. They expect the tips from the customers to make up the difference otherwise they won't be able to make a living. What kind of whisky does the man expect to be offered?
