I need to book a train from bishops stortford to Cambridge on Saturday arriving in Cambridge before 12:30.
I have TR4594, leaving at 11:29 and arriving in 12:07. Is that OK?
I actually need to leave after 20:30 on Friday. So whatever is closest to that time will be fine. 
Okay. The TR4549 leaves at 21:29. Will that suit?
Yes that works.  Can you book it for 5 people and send me the reference number?
Ok I have 5 tickets booked on TR4549. Your reference number is NTPYZBY4.
Thanks! Can you also check and see what 3-star guesthouses you have?
We are listing four guest houses. Which area of town are you looking for?
The east part of town, it should also include free wifi. 
I'm sorry but there are no guesthouses that I can see on the East side of town, can I look in a different location?
Yes, are there any 3 star guesthouses in the west that include free wifi?
Yes there is Hobsons house is in the west and has free wifi. 
Okay, I need a hotel for same group of people for two nights starting Friday, and I'll need reference number, please.
