Wilson Parking - Nishi

Last Saturday night the Payment Station outside the lift to this carpark was "Closed", an adjacent sign advising customers to pay using bankcard at the boom gate.

I was most unimpressed to find I was charged a "Processing fee" in addition to the cost of parking. What's more, I had no choice but to use this system, thus being penalized for the Wilson Parking machine - which DOES have a choice of paying by card OR cash - being "Closed".

Is this yet another way for this company to fill their coffers??? Surely, charging extra for an enforced use of bankcard should be illegal?
