My son recently had need to visit a walk in centre, being ill but not sufficiently so to waste A&E's time. Since his last visit, some time ago, a parking charge system had been installed at the walk in centre. Not being aware of this he had no change for parking and the receptionist advised him that the nearest place to get change was the shops which were some distance away. He drove there to get some change, this turned out to be a mistake. On his return the parking machine told him he had been in the car park for under 20 minutes (or whatever the free 'drop off' parking allocation is) and no fee was due. He was unable to pay, left and thought nothing more of it. Another mistake. The parking fine duly arrived.
At the moment he is going through some difficulties and decided just to pay up before the specified date to avoid a possibly greater fine later.
I can grudgingly accept the idea of paying for parking at hospitals for visiting but to charge for somewhere like a walk in centre which, by its very nature, is being used by ill people often with other more serious priorities is just plain wrong.
Never mind, it all adds to the GDP and allows people* to claim a growing economy.
* Other terms are available. I used this to avoid politics.
