DH is currently on jury duty. He has to pay for train tickets to the court every day and buy his own drinks/lunch etc. Which is fine - he'll get fully reimbursed when his service ends.
I was thinking, though, what do you do if you're on a very low income, or benefits? His transport/basic food is costing him around £10 a day. If you're on benefits, over a fortnight that's almost all your money gone. What do you do for grocery shopping/bills etc? It's all very well to say it'll be reimbursed but if you've noone to borrow it from and no savings, you're fucked. And if you refuse to do it, you could get a £1,000 fine.
It seems very unfair to me. Saying you can't afford it isn't a legitimate excuse to be excused, either. Surely it needs looking at?
