Directly opposite the shop there's a rather large temporary ticket office. If you come up from the station, turn right to head towards the West Stand and it will be on your right.
I just don't believe that ticketing staff would leave someone with a valid ticket left outside the ground, and certainly not due to a faulty printer. As I say - the ticket I have here has a timestamp of 14:48 and there were other machines printing away at the same time.
Presumably you have...
So someone was left outside and couldn't get into the ground?
I'm sorry I don't believe you - I have a ticket right here printed at 14:48 from the temporary ticket office outside the Amex on Saturday.
