U: Hi! I'm looking for a train to Norwich on Saturday.

S: What is your departure site and time?

U: From Cambridge and I want to arrive by 20:30.

S: I have a train that would leave at 18:36 and arrive by 19:55.  It's 79 minutes long and costs 14.08 pounds.  Would you like me to book it?

U: Yes please, book it for 7 people.

S: All booked and ready to go! The reference number is RJVNE0PT.

U: I am also looking for a place to stay. Can you find a 1 star hotel for me that is a guesthouse?

S: Unfortunately, there are no guesthouses that meet that criteria. In the area, there are 24 guesthouses, some of them cheap, some expensive. Can you narrow down your choices?

U: If there are no 1 star guesthouses, please find me the cheapest one that includes free wifi.

S: Alexander bed and breakfast is a 4 star cheap guesthouse with free interenet and parking located in the centre. Does that work for you?

U: Would you please verify that there will be strong water pressure in the shower?
S: Past guests have said that the water pressure is low when taking a shower. Anything else I can help you with?
