Parked without payment of parking charge

Ok Sir ..thank you for your guidance ..

If there was no exempt activity I can't see what you have as a challenge, and as I said Havering does not reoffer the discount so making a challenge just to ask them to use discretion for being by the shop is likely to just throw away £55.

Maybe there's something you haven't told us though.

OP, the PCN was served on 17th.

The discount ends of 30th, this is the end of tomorrow.

At this stage the evidence is all against the driver who'll have to decide what to do pretty sharpish.
