As my ticket was once again rejected by Southeastern's HS1 ticket barriers at St Pancras yesterday morning, I decided to enquire why.... "Is my ticket valid?" "Yes!" "So why do your ticket barriers reject it?" "I apologise for the crappy ticket barriers..... we have so many tickets to upload, we're busy uploading..." I don't believe that final statement - I suspect they just don't give a ****. I continued on my journey and the Underground barriers accepted my ticket without any problem at all. On my return journey (actually another single, going the other way), the St Pancras barriers rejected it, as did the barriers at Stratford International where I broke my journey. The suggestion at Stratford was that the starting station wasn't a Southeastern station so that was probably why the barriers were rejecting it. Finally, back at Gravesend, I had the satisfaction of seeing the ticket open its first barrier of the day! A tedious experience to say the least, although slightly compensated for by my technique of buying a ticket to somewhere I'm not going saving me money. So, if anyone from Southeastern is reading - sort your crappy barriers out, because it even winds up your own staff.
