I went from Hayes and/or Harlington to Hackney Central the other day,
changing at Shepherds Bush. With my 2/3 travel card I expected to pay
£1.10, and then get the overground for nowt.
But Oyster decided that my journey was long enough that it must have
gone through zone 1, and charged me £2.70.

Next time, I am wondering if I should find a bus and touch in on it,
and immediately exit the bus, in order to cancel the outerchange.
Would that work? Anyone think of a better way (apart from walking from
Holland Park?)
