I'm sure that there is a sign up on the car park telling drivers the rules of the car park.
Not that I am saying it is legal for them to issue penalties for infringement of these rules.

They have their own personnel who go round checking that cars have parked in the bays, and that you haven't overstayed the time limit. I'm not sure if the shops on the site pay the company to oversee the car park....but it is close to the town centre and as such is open to people abusing it by parking too long.
