Yea, you can ignore that.

I was getting "Penalty" and "Parking" mixed up...

Yes but does it say penalty charge or parking charge?

IGNORE ,TOTALLY. Last Xmas, someone using my car's missus was suffering from bunion problems,and the walk from most spaces was too much. So said driver ( who I do not /cannot identify) ,decided that she was as entitled to use of a disabled space as some of the ones seen almost running into the store from other disabled spots parked in one.
Coming out they found a T&C notice glued to the screen. As RK ,I've had some letters & invoices.All ignored ,including last one which talked of small claims action . Be nice that - counter claim - removal of glue/ removal of rain x from screen.Re application of rain x, loss of use whilst screen being attended to and a penalty for the offence. Then of course the threat of private prosecution for either interfering with a vehicle ,or criminal damage ,against the operative personally . Then there's Asda- failing in duty of care ,in allowing T & C operative to cause damage ( namely affixing a notice using adhesive to screen,causing a safety hazard) .Possibly also sign age problems,as the only sign mentioning penalties is outside the entrance, depending on not being obscured by persons exiting the store . Of course the ultimate deterrent is a letter to a local paper, mentioning that that parking is a contract between driver( not RK) and store and that RK is not under any liability to name driver,might cause that much of a rush on problem parking that the store might regret any action,as they'd be overwhelmed with folks ignoring their threat letters .

I may be poking a stick into a hornets nest here... but why the Sam Hill did he court the wrath of the parking wombles when he wasn't actually entitled to park in that disabled only space?
I have virtually no cartilage left in either of my knees and often it is a struggle to walk around supermarkets but I do (I know I'm a brave ikkle soldier) I don't have a 'blue badge' so I stay the hell out of blue badge 'territory'...it isn't rocket science.

Desperation I think. He'd been up all night in his living room chair, unable to tackle the stairs, and had only gone down to collect the prescription he'd been given to treat it.

Definitely not something he does on a regular basis.

It's this lot:

Probably due to common sense. At my local supermarket there are probably 20-25 disabled spaces, always 10+ clear every time. If I had a nasty but temporary injury which rendered me roughly as 'disabled' as a blue badge holder I would use one if I felt it necessary, in the same way as I will exceed the speed limit when I feel it safe and appropriate to do so, run amber lights regularly, etc. I guess not everyone obeys every little rule especially when they seem a bit autocratic.

OP SAID "from Town & City Parking (TCP)."
A bunch of shysters who hide in Perth, UNDER Scottish LAW. The next step is to pass it on to an English agency to make all sorts of threats to the RK. Things like debt collectors ,and small claims procedure.
All sounding very legal ,but on the back of a "PARKING CHARGE NOTICE"( T & C DON'T OPERATE,to my knowledge in council parks) . In fact, by using adhesive to glue the notice to a windscreen ( only way they can make certain it don't get blown away) ,its criminal damage at the very least. I'm getting ready for their next episode. Although I'd bet that after three goes, they've decided that this one won't crumble.
Edit to add
notice an addition from OP
"
Issued by a private firm not a council",and he did notice that it was "Parking" ,not penalty ,so T & C get another Nil points ( or pounds ), if OP JUST does nothing. Of course they'll threaten debt collectors/home visits & small claims court, with no proof.

An utter bunch of


I guess some gullible people might be duped.....
