I recently sent an email to our local council Planning Dept. as every planning application was listed as ‘Planning permission is being sort’ I told than the correct spelling and received a reply asking which application I meant.
I told them it was all of them! The spelling has now been corrected on all the notifications which must have been a very long job.
But I think your sign is a typo that nobody bothered to check.
1 must look out for that one AuntieFlo though I guess they will rectify it soon or so I should hope.
Or perhaps a genuine Gym Member might approach them to enquire if the charges apply to them as parking is only for Permit Holders and Gym Memembers? Either way, there will surely be a few red faces amongst the signage production.
