Couldn't use your links, but a review of the photos on the council's website shows you bang-to-rights. Can't see anything other than a plea for discretion.
IMO, if you refer to CEO's turning a blind eye, shop staff parking on DYL and you having parked here knowingly but without issue then not only would these not carry any weight, you'd probably find CEOs queuing to get into the road to get their day's quota before 9am, especially anyone caught by the implication ofyour 'blind eye' allegation.
