Yay! 
It was a pub car park last night. Went to collect this morning and had a ticket. Now, as it was a private company who witnessed my car being parked for a grand total of 5 minutes according to the ticket, I assume I just chuck it away and ignore any threatening letters?
From what I understand, these companies like to make threats and make it seem like they'll screw you over if you don't pay. However, for them to even consider being able to fine you, they have to have indisputable proof it was you who parked the car, and even if they do you're only actually liable for what it would have cost to park there. Correct?
