There are several, do you have a specific time you'd like to leave or arrive?
Can you help me find a train to london liverpool street? 
Train TR5154 leaves Friday to London Liverpool Street at 5:59 and arrives by 7:27. Would you like me to book this for you?
That works. I just need one ticket. 
Your booking was successful, the total fee is 16.6 GBP payable at the station. Your reference number is: 0XOVBBAJ. Will there be anything else today?
Yes I need to find a guesthouse that has a 4 star rating, I hate dirty hotels, don't you?
What area would you like to be in?
I am interested in staying in the south.
I found 2 guesthouses in the South both have a 4 star rating. There are two price ranges cheap and moderate, which do you prefer? 
I have no preference. I need to book a room for 2 nights starting wednesday.
I suggest rosa's b ed and breakfast. Would you like to book that?
Yes, please and let me know if the booking is successful.
How many people will be staying?
Just 1 will be staying there. I do need the reference number.
Your reference number is VFXJ5FEM.
Ok thank you that is all I needed. 
Okay. Thank you for calling.
