She explains: 'When I talk to my friends about the hours I have to work when filming, they always say their nine-to-five routine is hard, too.
I realised that at the age of 26 I had never really had a "normal" job, so thought I'd give this a go for a week.'
As well as stints on reception, Launch had the actress researching product placement opportunities.
So will she be giving up acting and joining Launch?
'Working those hours was really tough,' she says. 'I enjoyed it, but I've had enough for the moment.'
