I was going passed yesterday about dinner time and saw the queue. I parked up asked the security guy if they were selling over the counter which he confirmed they were so I queued up with about 50 others.
It seems that due to the on line ticketing issues they decided to sell over the counter two days early but not publicised it as they did have the staff as it was a last minute thing.
I normally buy on line for games like this but as there are 4 of us all season ticket holders and we want our 4 'spares' seated together I went for the over the counter option which I was originally going to wait till Friday.
It took me 45 minutes to get to the counter and there were 4 serving and two on the phones. The queue was longer when I left than when I arrived!
Only thing was that they didn't hand over my 4 spare tickets they are going to post them...this was odd and a bit of an inconvenience too for various reasons but now all our ticketing requirements were sorted yesterday rather than Friday
