I used to work on the switchboard at the BBC in the 90s. “met” is stretching it, but I spoke to lots of celebs on the phone. Most of them were nice, but Jim Davidson was an obnoxious twat to everyone (no surprises there, this was when he was hosting big break and the generation game).
I had a bit of a run in with Esther Rantzen. It was generally understood that you couldn’t just put members of the public through to celebs/ or the offices of TV shows. Esther got wind of the fact that we wearnt putting people straight through to the That’s Life office and called the switchboard to moan about it. It was me she spoke to, and she was really condescending and holier than though about it. We put a note on the whiteboard telling all the switchboard operators they could put people through to That’s Life from now on. I think it was 24 hours before Esther realised what she had let herself in for and told us to stop putting calls through.
