Is this the world's oldest con artist?

What do you do when an 88-year-old lady approaches you at the cinema and asks if you'll pose as her carer so she can use her 'get in free card'?  I knew she was 88  because she told me several times before we'd even reached the till.  I tried to explain that we were seeing different films (she 'Lincoln', me 'Les Miserables'), but she feigned a hearing aid malfunction.  Our cover was blown at the ticket point precisely because of our disparate choices.  I can count on one hand the times I've thwarted authority.  Now here I was in this aged 'Thelma and Louise' scenario wondering if the authorities would be able to tell which of us was 88 and would I be sent to an open prison or, even worse, made to sit through 'Lincoln'. The cinema manager appeared. Clearly, he recognised her immediately as a persistent felon. She waived her walking stick as if challenging him to a duel. She repeated that she was 88-years-old.  He refused permission for the free ticket. What could I do?  I offered to pay for her. The manager's heart strings started pinging and before I could fumble for the £10 in my purse, he overturned his decision and we were through. He tried to make her promise she wouldn't break the rules again, but by now she was already edging along row H in screen 1, minus her carer.
