I had a friend on benefits (JSA, I think, I don't know the details, it was years ago. )
She volunteered at some kind of day centre (Not sure if it was helping with adults with SEN, or if it was a kind of Job hunting, skill improving club) The clients knew that she had the same income as them, as they were on similar benefits.
Yet she seemed able to go away on 'holiday' and they couldn't afford it.
They sat down and looked at what they were all spending money on, and discovered that they were just choosing to spend on different things, and the occasional beer, cigarette, bag of chips, CD or DVD, which they bought, and she chose not to in order to save, allowed her to afford the 'holiday'.
She said it was an eye-opener for all involved.
(The 'holiday' was a religious pilgrimage, sleeping on a church hall floor, where the unwaged paid a reduced rate, so didn't cost that much. )
