Strood Retail Car Park: Has anyone been caught out again?

I ask the question after going there again myself recently and discovering new signs, which clearly state - highlighted - that you will be fined if you leave the site.

You may recall there was a big hoo-ha about people being fined there before, for leaving their car there while they nipped into the high street The upshot being, as far as I can remember, was that after so many complaints and fines being refunded, the rules were relaxed. However, this new sign says differently, as indeed, does a gentleman on the UKPC enquiry line, who I spoke with to clarify the situation.

So have you been caught out, believing you can stop there for a few hours, for free, and nip to other places too? Or do you avoid the retail park and go elsewhere anyway? How busy are the other car parks in the area and do you have to add time to your journey to get the them via the one way system? (Which was a nightmare when I went - spent longer on that than I did in the shops!) 

And while I'm on the subject, what's with this "No Return" within such and such a time on these car park signs? Small car parks servicing a small row of shops I get - but supermarkets?? Morrisons sign from their Strood store says 'No Return within 3 hours' (yes, I moved over there, got my shopping and then went to the high street!) So, driving away I realise I've forgotten something I simply must have - but can't go back to get it until three hours later? What's that all about? Are we at the mercy of draconian retail jobsworths, fixated with us daring to use their free car parks? For parking in? How very dare we?! Serves 'em right if we go elsewhere ...
