Re: Ive got a solution...
I've long been an advocate of getting unemployment benefits on a card, which can be used in certain retail outlets or for certain products and services. This has a huge advantage over the current system, where benefits can go on lottery tickets and 20 B+H, or on a piss up at the local, only for the claimant to go cap in hand to the JobCentre and claim for a Hardship allowance.
The additional price of a ticket to an interview can be added before or after the time, and the card be queried as to whether it was used to actually buy that ticket. This will help in fraud cases, where someone "says" they need a £20 ticket, but just gets a lift with their mate.
Problem solved!
