Four-minute delay on the tube from Paddington to Waterloo going home last night. Caused me to miss the fast connecting train home to Hersham. The train I did manage to get on was one minute late, though that was outside of TfL's network. Nonetheless, the overall delay to my journey caused by TfL's tardiness was 27 minutes, which equates to £67.50.
It looks like a glorious weekend and week coming up, so I'll leave you with some good news, for a change: TfL's rolling out some more air conditioning.
