Traffic stopped me getting the 08:24. The 08:54 was five minutes' delayed in arriving at Hampton Court, but that didn't matter because it always arrives 10-15 minutes before it is supposed to depart. However, it had accrued three minutes' delay by the time it arrived in Waterloo.
I then had to take a later connecting tube than I should have (that old story). This tube arrived at Waterloo a minute later than it should have, and at Edgware Road three minutes late. Total delay this morning of six minutes for £15.
