Not fines, invoices from greedy grasping companies who want to charge in excess of £100 very often in cases where you have done nothing wrong (not even outstayed your welcome).
So, talking of horses, get off your high one!
I agree with paying a reasonable fee for parking. All the parking invoices I ordered Mrs S have had were as a result of a parking company trying their luck.
As for you not having had a "fine" for 35 years, TBF, these rip-off merchants have only been operating a comparatively short time. I have also driven many hundreds of thousands of miles in my lifetime, some abroad. I have never had a parking fine/ ticket/ invoice abroad.
Most of them have been picked up over the years by Mrs S who drives a lot for business and uses such car parks at least once a day.
I resent both the companies trying it on with innocent motorists and you for implying these invoices were deserved. They were not.
