Slow news day I admit, but I just remembered that I 'met' David Walliams in Charing Cross when over in the UK for an exhibition. I did the whole "I know I know you but I can't think where from" bit - and he knew I was, giving me a huge "hello!" and walking on past. He seemed a pleasant fella.
My father in law (RIP) went one stage further, he met Eric Bristow in Stoke and asked him if he was still at the factory.
I hear celebrities can be quite horrible but struggle to recall meeting even one of this type (it may come) - so, what famous people did you meet that were nice, or indeed, not nice.
Oh, I did the same with Windsor Davies in Tottenham Court Road many years ago, and he responded with the most fantastic "lovely boy" expression!
