Car Park PCN - with a twist

[anothernameitist]

Visited a supermarket yesterday.

I didn't park over the stated time and was in a parent & child space legally.

Looked at signage:

Supermarket sign says £60 for misuse.
Car Park company signage says £75 for misuse

Signs next to each other too.

How would that all "add up" in court.

Take the Supermarket one.

Every little helps.
