Given a travel related situation, and given a specific question about the situation, summarize the question into a title

Ex Input:
I am travelling from London Heathrow Underground to Norwich, UK on the 18th of June 2017.  For this purpose, I purchased tickets via trainline.com and these were delivered to the USA  (perhaps it was a bad idea, but its done now!).



I am confused as to how to use these tickets/this ticket.  The folks at Trainline.com were unable to help me via telephone. I noticed that when I use Trainline's route service, this was returned:



So the ticket(s) I have:


Where do I use them? At London Heathrow underground or elsewhere?
Should I get other tickets for the tube journey between Heathrow underground to Liverpool street station?
Related: Where exactly is Heathrow underground with relation to terminal 2?


Please do let me know if I can improve this question in any fashion.

I've asked a couple of times in restraunts but I guess I failed to explain what I actually want after all. So, my question is - can I ask to include tips to the bill in Israel or should I instead always carry some cash?
