I used the long stay car park, having booked on the Internet and printed out the details. On arrival it seemed that there was a problem with the barrier(s). One barrier was permanently open and a lady security attendant was "checking" cars as they went through. I said that I had booked on the Internet and was ushered through without needing to show any proof. No problems finding my car I noted where I had left it, but was unable to leave the car park. The cameras failed to recognise my number plate and I had no "ticket" so the barrier didn't open. I pressed the help button and was let out after proving who I was. So, no interrogation entering the car park, but difficulty leaving. Shouldn't it be the other way around?
