Introduction
This goes back to when I worked for the Council. I was an "essential car user" and had an "authorised users only" parking space in the car park, which was a fair distance from the office, up a hill and down again.

The car park was handy for the main HQ though, and there were a lot of people who would just arrive and expect a space and the attendant would do his best to help.

The chap in the space next to mine couldn't face the daily trek over the hill, so he got another space closer, by getting his staff to park the office Mini up there! His daughter then started parking in his space (and she didn't work for the Council at all!)

Then someone else got that old space so she started parking in mine. I asked nicely, she ignored me. I asked her dad (who was more senior than I was, then) and he ignored me too. So I wrote this

Ode to Illegal Parkers
When I use my car I park it
in the car park near the market
There's no need for me to race
cos I've an allocated space
But I've got reason to complain
Read on and I'll now explain

It's handy that I get there early
cos later there's a hurly-burly
of people working for the region
(whose numbers, it would seem, are legion)
who think a sign saying "authorised user"
means "first man in, and last's the loser".

If you must go out in the day
on return, to your dismay
you often find some selfish lout
has nicked your space while you've been out
there might be other space, with luck
but if there's not, you're really stuck!

Now, you might think that's bad enough,
but what's particularly tough
is that some people are just stopping
and nipping off to do some shopping!
They've no connection with the Region
although their dad thinks he's a heid yin!

The dad once used to park up there
but couldn't face the daily stairs
so now he parks in Market Street
to save his poor wee tired-out feet
His former parking space seems right
for an office vehicle overnight

But now and then, it seems, his daughter
doesn't park where she really ought ter
but takes a space and parks for free
and makes life difficult for me
In future, madam, think of us
feed a meter, or get the bus!
