RE: Pricing
I don't normally stick up for GNE but on this i'm with them. They're offering a cheaper ticket for a particular age range... if you want to take advantage of it you need to prove you fit the criteria. I'm sure they gave several different option to do this in the bumff I was reading. Also as for carrying a passport around when i was young my mate used to have to carry theirs with them down the big market to get into bars.......... which i would say is a lot more risky of losing it than showing it to a bus driver when your sober! And to my knowledge no one ever did lose one
