I had to do ExCel - Limehouse and then, later, Limehouse - Bank by DLR
earlier this year. The machine at Limehouse refused to touch me out and
told me to consult the ticket office. There is no ticket office and no
call button to talk to anyone. Because I had an unresolved journey I was
charged maximum single fare (the nice man from customer services said
that an Oyster Card debits maximum fare when you touch in and refunds
when you touch out.

So, there I was. Started the trip with more than enough money for both
legs, ran out halfway. It happens.
