Loads, few off the top of my head:
Gordon Ramsay, exactly as you expect him, told me to fuck off after I told him a ate packet minestrone soup. Fair I thought. He was funny and matter of fact and did everything I asked him to do even though it was mainly stupid.
Nigel havers: absolutely lovely, again very pleasant and willing. I told him my Nanna loved him and he took it with good grace.he had to hang out of the back of an ambulance and he was on board with that.
John Prescott: funny story where I actually got trapped alone with him in a school gym. We got locked in. He was lovely and we had a laugh.
Lots of sports stars from the era of Chris akabusi, Sharon Davies etc, all pleasant enough.
Michael winner: was truly an absolutely dreadful man. Horrible to everyone around me and around him.
David Cameron: he was nice but it was a very rushed visit and his awful pa was doing the ‘sleeves up David’ shots with him and he seemed a bit fed up with it all. Happily posed for a photo with one of our guys even though he was really busy.
Prince charles: lovely although totally used to dealing with situations involving lots of people. Also did whatever asked of him photo wise. Same for princess anne.
That’s a few off the top of my head. The only awful celeb that springs to the front of my mind was Michael winner only because he was so foul.
