Pook, I got in enough shit from BBC/Tumble plc lawyers from posting pics of the days filming at work. I’m saying no more.
No encounters with the Tumble, but anecdotally from my time at the beeb, it always seems to be the ones who are most genial/avuncular on screen who turn out to be the most miserable bastards when the camera is off. There were a few who did their usual schtick in front of the mic but the speed of transformation was startling once the interview ended.
Worst pissheads were the kids telly presenters too. Helped them deal with the pain, I guess.
