U: Will I be able to get a train out of London Liverpool Street that leaves after 15:15, or will I need to use a different station?

S: What day would you like to leave?

U: I need to be there on Friday.

S: There is no train leaving at 15:15. However there is leaving at 15:39 on Friday, would you like that one?

U: I don't have to leave at exactly 15:15. I just need to leave after that time and travel to Cambridge.  What are my choices?

S: There is a train at 15:39 and every other hour after that.

U: I would like to book it for Friday for 7 people and will need a reference number.

S: Booking was successful, the total fee is 116.2 GBP payable at the station. Reference number is : M0H2YQDY. Is there anything else I can do for you?

U: I am also looking for a place to stay.  With free parking and one star.

S: I'm afraid that I didn't find any. Would you like to try for a different star rating?

U: Try for a 4 star instead.

S: Sure thing I would suggest this one arbury lodge guesthouse.

U: Are the staff the most welcoming?
S: At the Arbury Lodge Guest House, the staff is known to be very friendly and welcoming. They will accommodate your needs. Do you want to book a room?
