Free cinema for crips
Well, kind of.
If you're in receipt of DLA, or you've got a disabled person's railcard, or you're registered blind, you can apply for a Cinema Exhibitor's Association card.
For a one-off administrative fee of £5, you get a card which entitles you to a free cinema ticket for the person accompanying you. And it's valid for three years. It's even notched along one of the short edges to "aid recognition" if you're visually impaired. (So, no danger of handing over your credit card to the box office staff by mistake, then.)
Of course, this is actually intended to prevent you having to pay for two seats if you're not able to go to the cinema on your own. But there are loads of people who are eligible but can manage quite nicely on their own, thanks very much, and who can therefore split the cost of the single ticket with a mate and/or demand that said mate supplies them with vast quantities of popcorn, jelly snakes and over-priced fizzy drinks in recompense for the free ticket.
