It took me about an hour to park the car and get to my office this morning. Getting into the car park was easy - my pass card opened the barrier. The car park was full so I tried to leave to go to another car park. Actually the car park was had plenty of spaces but they were all in the roped off empty upper floor of the multi-storey. The top floor had been closed due to the risk of ice.

I drove to the 'out' barrier and swiped my card but the barrier failed to open. A queue of cars started to form behind me. A few other people tried the barrier but it wouldn't open for them either. We phoned security and waited for them to arrive. It took 3 people and a lot of trial and error before they managed to get the barrier open. I eventually managed to leave and find my way to another car park which had some proper spaces, which happened to be a decidedly non-icy top floor of another multi-storey car park.
