U: Can you help me with train schedules?

S: I certainly can. What did you have in mind?

U: I am looking for trains that depart from cambridge and go to broxbourne.

S: We've got several trains going that route.  Is there a particular day or time you need?

U: I need to go on Friday.

S: What time will you be departing from cambridge? Also what time do you need to arrive in broxbourne by?

U: I just need to arrive by 18:30, the departure time doesn't matter.

S: I have several that arrive before 18:30. I have one that arrives at 16:01, 17:01, and 18:01. They all leave an hour before arrival time and are 17.90 pounds.

U: Can you book the train that will arrive at 18:01 and I need 4 tickets.

S: Your booking was successful and the total fee is 71.59 GBP, which is payable at the station. Your reference number is D3L643YZ.

U: Thanks. I also need a guesthouse to stay in in the north.

S: How about the acorn guest house?

U: Does Acorn Guest House have spotless bathrooms?
S: One guest said that the bathroom was very clean. But another said it was a little unclean. But the people working there made it clean swiftly.
