On Saturday (14/06) just after 8PM, I had to pop over to the store on Slough High Street. I've parked in a designated bay on
Wexham Road, Slough, as someone was just leaving the space. I was parked as the last car in the designated parking area just before junction with Grove Parade and the 'Controlled Zone', and considered myself very lucky (as other people normally park there on single and double yellow lines). I've checked the parking restriction hours (8AM-6PM, so I'm outside them) and went off to the shop as I wasn't planning to stay there for longer than 15 minutes. The location was always a pay and display area, and I have assumed it still is.
I went to store, came back and noticed a PCN stuck to the windshield.
Upon checking the added text at the bottom of the sign. It is now not only pay and display (in restricted hours) but also permit only location. Clearly my mistake for assuming.

The area is now pay & display AND restricted to permit holders too.
It is a company car (it is a micro business) and this was a private journey.
Any suggestions for challenge or shall I accept, pay and never set my foot again on High Street outside of the restricted time?
