"Car Parking"

On my visit today, tried to pay using the old round pound coin (all I had). The ticket machines seem to have been programmed to accept only the new coin as my old coins were rejected. Bit of a cheek really as the old coin is still legal tender and as such should still be accepted, up to the cut off day. Not amused as I had to faff about getting some new coins...and all this having waited to park for over 20 minutes and then paying what some would consider, a high price for just over an hour parking.
