      They went to a pub (酒吧) about one kilometer away. It was lunch time and a lot of people were in the pub.
The owner (店主) was selling drinks at one end of the long bar (柜台) while a waiter (招待员) was selling
drinks at the other end.
      "My friend and I can't agree," Jack went up to the owner and said, "I say there are two glasses in a litre (升)

      "Thank you." said Jack, and went over to Joe. He was standing at the other end of the bar.
