I would be grateful if anyone could give me some advice please: My friend went to B&Q yesterday, parked and went next door to use cashpoint returning to B&Q to make a purchase. When he returned to his car less than 50 minutes in total he had recd a Parking Charge Notice from TPS. It was only then he noticed a guy in the car park photographing cars. On the PCN they have ticked the box "The driver was observed leaving site whilst vehicle remained parked on the premises". I've been down and had a look at signage and it clearly says that you must not leave the site whilst car is parked. Is there any defence he can use not to pay the £90 / £50 charge. Can we ask for proof that they saw him leave the car park and if htey provide photos are they allowed to photograph you without your permission; or can we use the argument that the charge is unreasonable for the potential breach. Any help would be very much appreciated of how we proceed - we haven't done anything yet and my friend has a heart condition and this has really caused him so much anxiety Thank you so much
