I've met Angeline - and although I'm not a huge fan of her presenting style, which can sometimes come across as a bit 'aggressive' and over-confidence, in person, she's really quite different to her presenting style. She seems really nice and welcoming - as is Nick.
The only two I've met that are like their 'on-screen' personas is Carol Roache from Jewellery Maker - she's just as gobby and annoying in real life - and Dave Troth. In fact, I'd say Troth is worse. He comes across as REALLY ignorant. I don't think it can be put down to shyness either because if he was shy, I doubt he'd have the confidence to spend hours and hours on our screens each day.
