These are the signs displayed in the Service Bay (not quite where I think Hairylee parked). They are not the official Parking monitors of LCC, and therefore will not have any authority to charge you a penalty or take you to court .... unless to recover their losses, which they don't have due to no charge for parking in this particular area.
I would completely ignore it, however, I am not Hairylee and she may feel threatened and pay up which is understandable.
