I've found another way in which Oyster incorrectly charges people too
much.

On Tuesday evening I touched in and got on a train at Waterloo. A few
minutes later we were told that there was no driver. So I got off,
touched out, found the next train on the departures board, touched in,
and travelled.

The result - I was charged for entering and exiting at Waterloo, and
then charged again for my actual journey.

Now, I've emailed the helpline and I'm sure I'll get a refund in a few
days, but most people aren't aware of how error-prone Oyster is and
consequently that they should check their journey history. I wonder how
much TfL and SWT made from that train full of people going nowhere.


It's not an error, the system is operating as programmed. (You're a
programmer, no? Technology, including Oyster, doesn't just do it's own
random thing.)
