That happened with mine last night. Brought it to the attention of the gateman, and he waved me through - this was about 15 minutes before kick off.
I was going to see if this happened again next week on the basis it was a one off 'rogue' occurance before getting in touch with the club via e-mail.
Problem didn't happen at the Huddersfield and FC games, so may fire off a mail on Monday in view of the above.

Just depends who's the biggest

Should be in reality the season ticket holder.

probably right...my little lads ticket wouldnt work last week end at Latics game. That was West stand and a normal match day ticket. We moved to the next turnstile and his ticket worked, but mine didn't..so des suggest a turnstile problem

But the people getting in to find somebody with a printed ticket for their seat does suggest some other issue. As surely a fault with a turnstile barcode reader alone wouldn't result in a reserved STH seat being sold to somebody else at the ticket office?

Hopefully the issue has been resolved or it could cause some serious issues at Friday's sell out match.

Well I rang the ticket office Monday and they said the tickets were to be posted back to me but no sign yet. If they don't turn up tomorrow I can't go because there is no way I can't justify turning up early enough, given where I live, to get to the ticket office to try and claim my seat with the possibility its been sold to someone else.

Looks like another phone call tomorrow.

This is a total joke.
