We were passing through Leeds last month and pulled into this Greggs on Gelderd Rd for a snack. Now I've been before and I know you're not supposed to park outside of designated bays, but we were tired and hungry and there were vans shuffling in and out of the narrow car park so Emma jumped out while I left the car running next to the Biffa bins. Three minutes later we were on our way. Total bill for our two teas and chicken bakes now stands at £100. As I understand it this claim is to be regarded as an invoice from a private company rather than a formal PCN. What is the best course of action with these bandits?
