Free Parking?

Are you sitting comfortably? I am going to have a rant. 
First a relatively minor one...

This sign means the space is for disabled people, blue badge holders. Bob is so grateful for his permit, it means the walking distance from the car park to the door of the shop/church/theatre is reduced. My neighbour knows the hatched areas around the space means there will be room to manoeuvre her daughters wheelchair. 

These spaces are not for Joe Public, who is in a hurry and doesn't want to walk from the other side of the carpark. And people who park in such spaces should display their blue badge. 

So the other day, when we returned to our car outside a busy Sainsburys, and a couple pulled into the adjacent space and both jumped out, and set off speedily towards the InPost lockers, Bob called out in a cheerful tone "Hey! You've forgotten to display your blue badge!"
The man said "We'll only be two minutes, we are going to the InPost Locker" and the woman said "oh, I'm waiting for my blue badge"  I know not all disabilities are visible, and maybe she was 'waiting for her blue badge' to arrive...but as we drove away, I was pretty certain they did not return to the car after depositing their parcel, but walked towards the supermarket. Bad behaviour if you ask me.
But that is nothing compared to the utterly selfish people on the Norfolk coast this weekend,.

On Sunday morning, seven people, including four children were trapped on a sandbank with an incoming tide at Wells Next the Sea. This is not uncommon at this time of year, visitors do not heed the warnings

The siren sounded and the volunteer lifeboat crew scrambled to get to the station so they could launch a rescue craft - only to discover that holidaymakers had taken up all the crew's designated parking spaces by the lifeboat station. Which obviously delayed the rescue - where every minute counts as lives are at risk.

This is unbelievable thoughtlessness - I am grateful that this time, all the stranded people were rescued safely. Operations manager Chris Hardy said “Today, our crew experienced difficulties parking when responding to this shout.The restricted parking near the lifeboat station is clearly marked for RNLI crew and emergency access, and it is vital that these spaces are kept clear." He asked visitors to respect the restrictions staff, who try to enforce them. Parking issues persisted throughout the bank holiday weekend The crew pleaded again with people not to park in their spaces after more issues on Monday morning. "We are asking everyone, respectfully but very clearly: please do not park in or block RNLI access areas, emergency service spaces, slipways, gates or turning areas," 

Personally I feel that people who park in the RNLI Crew spaces should have their cars towed away and impounded, and be fined for reckless endangerment of life. I don't think people would park their cars in ambulance bays, or across the front of the fire station. Why do they think it is ok to regard these spaces at Wells as "Free Parking"?
