I went on Saturday and I queued twice, both times were less than 5 minutes - once for Dirk and the other for Chris Barrie.
The reason for the queues, the guys were really relaxed and chilled and spending time chatting with each guest. It was nice that people were not rushed through like a cattle market and the stars allowed to take their time. The other three I met, Burn, Robert L & Tony Head, I walked straight up with no queuing and again they were really relaxed and chatty.
Had a fabulous time personally, got a little crushed for about five minutes around the stalls but that soon eased off. Was very well organised and run with the SM crew being very lovely, chatty and happy.
Lets hope that SM do another in Sheffield next year.
