I was in the same boat, got turned away as I didn't have a ticket so hung around for an hour or so to finally get to see him with a small amount of people behind me and you'd have thought he was paying 25 quid to meet me to be honest.
My experience with Ade was that he started to sign in black pen before I had chance to request if it could be signed in bronze sharpie, however he did say the photo he was signing did look better in black ink of the ones he'd signed... I asked for a quick photo (of him, not with) but he said I should have taken that earlier (presumably whilst I was having said chat about requesting the ink colour...)
I did manage to get a quick photo (as he was about to sign the next person's photo in silver pen) and seeing as I was still stood there still having my turn (and didn't want things to end on a sour note) I took the opportunity to shake his hand and told him I thought he was brilliant in the Young ones and Bottom amongst other things, which he certainly was.
I've been a fan of those shows for 20 years and its nice to read of peoples good experiences with him, I just left feeling a bit deflated by the whole experience. I met Danny John Jules in April and found him to be the complete opposite, engaging and friendly and from what I saw, the last person in the queue was as important as the first and his line was just as long as Ade's.
I must add however that the signature (In black ink, not bronze) is very well written...
