I'm leaving out of Cambridge.
Great there are 70 trains, do you have a day or time?

Yes for 4 people please. I will need the reference number.

Can I have the reference number for the train booking please?
I have another train that leaves at 07:21 and arrives at 08:10 if that would be better?
That is not better. I would like a reference number for the 4 tickets already booked, please.
Sure thing. The reference number is L130XFN9. How else may I help?
Thanks. That's all I need. Have a good day.
You as well, enjoy your trip!
