I was at the HCTB signing in the Netherlands. Great that they sell the tickets now! Then it was just horrible. Meat had an hour. But the line was twice as long, so a lot of people couldn't get a autograph. And the 10 seconds is right. I was lucky, because there were some press, who wanted to photograph and do some tv shots. But the time they were setting up, it was my turn so I got 5 minutes with him. If I was one earlier or later, it would been 10 seconds. So if you wanna say something to him, rehearse the shit out of it. My wife wanted to say something and she only said "Uhm blah, ha jah". In such short time frame you must do it right the first time
Also take 1 person with you to photograph. At our signing he didn't do photographs because he got limited time. So I got real close at the signing and my wife took a lot of photograps and just hoping one is great. I got lucky because she got a photo where you see him talking to me and looking me in the eyes.
