Am I the only one who thinks managing to get to your destination on a train without encountering a conductor is a bonus?
Personally I wouldn't go out of my way to buy a ticket, if they come and ask me to buy one I will - obviously - if they don't then I don't seek them out.
Am I a bad person?!
I'd do the same, but it's a very law-abiding forum, and we won't be popular.
