Well colour me surprised and chalk up a victory for TfL! On my journey in to work today, I arrived at my change point in Wimbledon in time to catch not just my connecting tube, but an earlier one, getting me to the office six minutes ahead of schedule (despite that tube being held on three separate occasions for red signals).
Even though that first train did not arrive early, and even though TfL's Journey Planner seemed not to know of the earlier tube's very existence, in the interests of fiarness, I am deducting six minutes from TfL's bill.
Or, more accurately, five (since my journey home was delayed by a minute [no explanation]).
So that's £12.50 back to TfL. My whole world doesn't make sense anymore.
