Well first of all, you met LP - why complaining? other LPUers here haven’t met them once!
Then: I was at the meet and greet in dortmund 2 years ago and it was the same!
Its been a rule for a long time that you are not allowed to take photos while you get your stuff signed. They did this very early in 2001 up to 2004 or so and then changed it because of a time issue.
In 2009 they had a new rule that just 10 or so ppl were allowed to attend the meet and greet and 2 members were there but you had a quiite intimate time and could talk to them.
When you now have meet and greets with about 60 people or so, it takes a while to get everything signed.
For the pre - waiting. We had to wait about 30 minutes and did some games with hugo and maurice to kill the time until LP came out and signed our stuff.
But honestly, i would not want to get photographed like 60 times with flash etc, its stressful for the band too.
They were friendly at our meet and greet and said hi and everything but they also had to do press so there was not much time left.
As i said: be happy with your meet and greet!! You won it, got something signed and met the band!!
