Got a ticket for an overstay at a carpark in Southampton, since it was a private car park the so called ticket is actually an invoice. Unlike an official parking ticket which is issued to the vehicle and its owner, the invoice is issued to the driver. I followed up with a letter to the company saying that I did not know who the driver was at the time of issue (could have been my missus or me!), thus no further action was taken.
I was surprised how quickly they slapped it on the windscreen, because it again was only around 5 minutes which I thought they'd never bother me for!
