I put my ticket the the brand new machine, with scintilating blue LED display, in Cambridge's main city car park and it said, loudly: "Your ticket is unreadable!" in an American accent; a poor match of meaning and sentiment. Darlek would have been better: "Your.. ticket.. is.. unreadable... your... ticket.. is.. unreadable... "
Personally, if this was my project, I would have used Marvin's voice: "I'm ten thousand times less intelligent than you but I suppose you want me to read the other side of your card rather than tell you to turn it over? No, don't bother to answer that, I've already done it, life's do depressing."
