My parking place was moved when my "office" moved. I did not ask for this. I only found this out yesterday when an observant colleague informed me that one of our number had been clamped.When I read the small print on the permit I realised I was parked "illegally". My point is that for the last year, when the barriers were down,I was admitted to the car park by the key card that I have held for years. Would clamping me be illegal as the airport authority had admitted me in the first place? Any one care to comment?
