I get there and find it's a new build without any visible parking spaces, i assumed there were around the back of the buildings. She's seen the "no parking" sign and yellow hatching and parked 5m away from it half on a kerb so she wasn't blocking the access to the rest of the site. (would show it on google maps, but the images just show the building site!)
from her -
She gets out of the car, walks 5 doors down the row (road doesn't go that far) with a big red food delivery bag and gets back to the car to find they're doing up the padlock on the clamp.
Clampers were giving her hassle "pay up now or we're taking the car, etc" so she called the police.
On the way there i ring and arrange a recovery truck to take the car home for me (taking the clamp off without damaging it is quite legal).
The biggest idiot copper in the world shows up and sides with the clampers!
The residents who received the delivery show up wondering what the noise is about. They've asked my wife to bring food to them, she's allowed to be here. "Have to pay the ticket and appeal", "but we're the residents, we asked her tom come here, she has our permission to be on the estate", "have to pay the ticket and appeal", etc.
My recovery truck show up and leaves after getting the heave-ho from the copper.
Clampers start threatening "the moment i make this call to our tow truck the price goes up", "umm, no it's doesn't work like that, until the truck gets here, you can't charge us anything extra as you haven't done anything extra", copper chips in "oh, they can".
Wifes boss shows up with the £100 they wanted to take the clamp off and they fill in the paperwork. All this time they've been refusing to show their SIA ID "you've got the company name, what else do you need", copper was fine with this too.
Residents have given us the details of their site management company to take it up with and their contact details too to explain that they wanted her on the site and that she was delivering stuff to residents, which would then be part of the appeal to get the funds back, but i'm not holding my breathe.
Wife just forwarded me a pic she took on her phone of the area, mobile phone flash so the lighting isn't great, but obviously the signs are displayed and the area is well lit anyway. (i've tweaked the levels as best i could)
Red is the "keep access clear" sign by the hatch marks, green is the clamping warning sign.

From what we can tell they must have followed her onto the site and parked up as she walked down to the customers house.
Absolutely ****ing livid, nearly clocked one of the cocky ****ers with my stick.
