You maybe right that he did not take the payment becuase he could not
process a plastic card. I can't remember exactly now. I know the
conductors on the train have the facility. So, why can't the
inspectors have one? This is a bit strange, as I've just read the "new
fares" plan by Livingstone, where he is basically trying to discourage
cash payments. In US, not being able to accept a credit card would be
their problem, not mine. Well, the algorithm of how the inspectirs
work here and process fines seems to me a bit draconian, really.
