I'm slightly shocked people do it for so little
For most people, it all depends. If you're single and saving for a house or something, every little helps. If you're in my position with a young family and very little spare time, then they would have to pony up a whole lot more than is currently offered to make it worth my while, so I've not signed up to the rota. Horses, courses etc.
