anyone ever done any film/tv extra work?

girl at my work is trying to get me to sign up to an agency she's with saying it's in excess of £100 to sit around on your arse all day, which if i could work it in with also taking a day off work might not be a bad earner

alternatively look at how bad these "posed" photo's are -
