Spieluhr That’s a great story! Not surprised Gary Linekar is lovely.
I also saw Lawrence Llewellyn-Bowen at Gatwick once with his two daughters. He was very smiley and nice to people who spoke to him I’ve also met him and he was a delight. So friendly and funny. Very relieved because he was my childhood idol (I was a strange child)
I’ve met a few celebs, mainly at book signings so you’d expect them to be “on” anyway. They’ve all been nice but that’s to be expected for these sorts of events I suppose. Still, there are a few who appeared genuinely lovely:
Jeremy Kyle- (I was a student and watched a LOT of JK in the mornings with my best friend so we thought it would be funny to meet him) Very funny, put everybody at ease, really approachable
Rylan- An absolute peach. I’m not sure whose idea it was, but rather than the conveyer-belt kind of signing, he was in a penned off area and only one person was allowed through at a time. Meant he had a proper conversation with every person. He chatted to me as if he knew me, complimented my outfit, spent a fair bit of time talking before signing the book. I was supposed to be going on This Morning the next day (it never happened in the end) and told him this, so as I left he shouted across the shop “bye Bleach! See you at work tomorrow!” I felt like I was his friend 
Alexander Armstrong- Thoroughly charming. He was with Richard Osman, who was also very nice, but AA was wonderful. Incredibly warm and forthcoming with conversation. I was the last person in the queue and they stayed on for over an extra hour to make sure everybody had their books signed. Even though they’d had a long day, they showed no signs of impatience by the time I eventually reached them.
