they also say you should swipe your oyster as you enter a station even if
the gates are open, or you might have a problem at your exit station.
my local station gates are always open and I never swipe it, and I have had
no problems on exit.
I think it is a case of 'Big Brother wants to know where you are and where
you are going'.


I think that comment shows perfectly that the message about Pre Pay
isn't getting across.
No, it doesn't matter so much if you've only a season ticket on your
oyster card but if you're using Pre Pay, you'll be charged a lot more
than necessary for the journey if you don't touch the reader on either
the way in or out...
