I was a contestant on MC about 15ish years ago, and despite being in my early 30's at the time, I still looked like a teenager (relevant - not a stealth brag). I was also the youngest female contestant that episode.
John greeted me like a normal human being, but Eggggg held my handshake for far too long in his clammy little trotter whilst simultaneously grinning and looking me up and down like a hairless hungry butcher's dog eyeing up a fresh steak. I was instantly creeped out and wary.
Filming took two insufferably long days. The whole time, Mastertwat was cracking lewd, dirty jokes that forced innumerable cuts and retakes. By the second day, even the people who had been nervously/politely laughing couldn't take it anymore. It was just Eggggg, guffawing into the void at his own hilarity. The crew's deep dislike for him was palpable.
Completely disillusioned and not wanting to spend a millisecond longer in his company proceed any further in the competition, I made a point of giving Egggg the Paddington hard stare and calling him Craig anytime I had to interact with or refer to him.
Long story short, I threatened to walk out on day #2 when he massively ramped up the sleaze factor, made a nasty 'joke' about the size of another female contestant's nose (which made her cry), and embarrassed us all by association in the professional kitchen, where the actual working Chefs all referred to him as 'That Cunt'.
This was the point where I was reminded that I had signed a contract that forced me to see out the filming of the episode, AND that there was a non-disclosure clause in there too. The BBC have known what he's like, covered for, and encouraged his disgusting 'laddish' behaviour for a VERY long time.
