WHY DO PRIVATE PARKING COMPANIES TREAT THEIR CUSTOMERS WITH  UTTER CONTEMPT

It beggars belief that some companies like Parking Eye and Excel go out of their way to treat their customers like shit. Their business model is based on obtaining money by fraud , seizing upon the slightest transgressions with pernicious bullying tactics , relying on victim's apathy or lack of funding to fight back. They never listen to reason or legitimate excuses . Their unforgiving and aggressive attitude towards motorists is breathtaking in its zealous and  ruthless pursuit of lucrative profits.
Whereas most businesses promote customer care as one of its core mission statement objectives, private parking companies choose to have a hidden agenda to " screw the bastards " anyway they can.  Whatever happened to showing customers a little bit of sympathy and respect ?
These modern day highway robbers go out of their way to make life  difficult , awkward and miserable for the motorists. Everything they do smacks of deliberate entrapment to lead their customers astray.......to make mistakes .......and then hit them with the threats , intimidation and harassment to pay these deviously engineered albeit bogus fines. 
They are completely unhelpful in the extreme. Requests for information and/or explanations
are treated with contempt. Do they provide sticky-back tickets which adhere to the dashboard ? No. Do they choose to have a set up where payment for tickets is on exit ( not entry ) ? No. Do they allow overstayers to pay the extra on return to the car park ? Like hell they do. These are firms which have mind sets like a cruel sadistic tyrants.  
Name me one other company that " fines" its customers. Yes , customers may be asked to leave or be blacklisted. They will often be given warnings first about unacceptable behaviour. Many might well be chased for non-payment of goods and services , but in the main customers are valued because building up a strong customer base is essential if businesses are to survive in a world of highly competitive markets .
So why do private parking companies treat their customers with such contempt ? Well in many cases they have a captive market with parking spaces being at a premium. Demand will often outrun supply, and therefore if car parks are busy then it seems there is no need whatsoever to  envourage repeat custom. In other cases what does it matter if a car park is only half full. Clobbering just one unsuspecting motorist earns the same revenue as 50 paying ones. This racket has  almost become a licence to print money. Customers are like sitting ducks......fish in a barrel......there to be shot at time and time again.
The welcome sign ....such irony....always prominently displayed outside the car park ...is modelled on the " welcome to my den said the spider to the fly " scenario , or on Hannibal Lector's invitation  " let me make you dinner tonight ". Motorists are never viewed as customers but victims on which to feast..
