I parked in C.London as a visitor last week in on street parking. It was operated by Ringgo and I had a few issues getting the payment set up and needing to update my bank details. I went into my hotel yo connect to their WiFi and within that 30 mins I received a parking ticket.
The next morning, I bought 2 hours parking, knowing I got an extra hour free with my Blue Badge. What I completely forgot was that I had been advised to hide the blue badge overnight so the warden would not realise one hour free.
Both tickets issued as appropriate but how on earth did they do it!? Within 30 mins each time of my parking not been covered, they came and issued me a ticket on windscreen. I checked afterwards and couldn't spot any CCTV and not once did I see a warden in the area!!! Absolutely puzzled!
