I unwittingly strayed into a private parking area near Piccadilly Station in Manchester when dropping someone off. I'm a Mancunian. I know this City. This was never previously a private parking area so I was dumbfounded to receive the charge notice one week later. I went back just to check for signage and sure enough, there it is, so I paid it. How else could they patrol it, I hear you say? That would be there problem, I say, but I'm sure there are answers to that question for all these companies. Answers that they don't want to consider.
