U: I need a train to Broxbourne.

S: There are many trains available. Will you be traveling on a certain day or at a specific time?

U: I'll need to travel on Sunday, from Cambridge to Broxbourne, and I'd like to arrive by 10:15 please.

S: TR4249 leaves at 06:01 and arrives at 07:01 giving you plenty of time. Can I book that for you?

U: Yes please. I need to book it for 7 people. Can I please get the reference number after it's booked?

S: I have it booked for you. The total fee is 100.24 GBP and the reference number is JIXSCT7D. Is there anything else I can help you with?

U: Yes, I need a cheap place to stay.

S: Do you have a preference for the area, stars, internet or parking?

U: I want it to have star of 4, and include free wifi. It doesn't need to have free parking.

S: Does location matter? The Alexander is a popular choice in the center, but Rosa's is a favorite in the south.

U: I just need to know if they have clean bathroom so can you tell me anything about that?
S: Rosa's Bed and Breakfast are rated for very nice and clean bathrooms for each guest during their stay.
