Upon entering the car park, the driver found a space, parked up and entered the Costco customer service area. Costco is a members only store and as this was the first time visiting the driver had to queue for over half an hour before being able to complete the membership process to receive membership cards and finally be able to enter the store proper.
The Costco store is huge and as this was the driver's first time they spent several hours exploring every aisle before finally buying £450 worth of goods. There were further delays leaving the store as all trolleys are manually checked against receipts. Upon transferring the large number of purchases to the car and returning the trolley to the store, no other store was visited and the driver left the car park, allegedly exceeding the 3hr parking limit as the claimed duration was 3hr 26min.
At some point in the last few weeks the registered keeper (a different person to the driver) received a PCN through the post but they missed it initially and only opened the letter yesterday and showed it to the driver.
Can this be challenged? Do Premier Park follow the requirements of the Protection of Freedoms Act to be able to transfer liability?
