OK. My Chiltern Railways train to London was cancelled this morning. Actually, my stop was taken off the usual train.
The next train arrived into Marylebone just over 29 minutes after my original train should have done, to Platform 5.
My usual train arrives on Platform 2.
I got to the ticket barriers more than 33 minutes later than usual.
Should I waste a stamp on trying for a 30 minute Charter Refund? Hmmm.
