My intention was to go to the train station to renew my season ticket but my body was on auto-pilot and went straight past the barriers, checked for the next available train and got on it.
Realised that I was not meant to actually leave on a train when I looked around and the train wasn't as jam-packed as it usually is.
Tried to make it out of the train but unfortunately did not make it. Am waiting at the next station now to return to work....and hopefully to renew my season ticket on my way there...
Update: Thanks for all the comments. Nice to see fellow mindless numpties out there.
Just to update you all - I made it back to work in time, but as I got back to my station the queue to the ticket counter was painfully long...
so long that I got worried I would switch to auto-pilot mode again and hop on the train once I get my ticket!
Luckily I didn't and made it back in time but without lunch, I pretty much functioned on auto-pilot mode for the rest of the day!
