Hi, I have been following these threads with interest because, as you can guess, I was also caught out at McDs in Gatwick. I've sent my standard letter back and have now received the pretty red invoice as well as a letter saying my representation failed and the charge could not be cancelled - I suspect you may know the wording. I had intended to reply and just to repeat the same as in my previous letter, possibly saying more specifically that I was disputing the charge. However, reading all this makes me wonder: on the day I parked unwittingly to get a cup of tea, we were handed a flyer which mentioned the time limit. It mentioned no charges for overstaying, just that this was to enable other customers. Clearly we did not look for signs proving all the terms and conditions of parking in McDonalds car park. I've not seen anyone else mention this - not that it matters in the grand scheme of things I guess. Now I see that new signs are in place, extending the period. As my "PCN" claims that I "overstayed" and gives the times (less than one hour), but does not say how long the limit was - how does that work now that the times have changed? I have no intention of going into this with them and will stick to my standard letter, if anything at all - it's a busy time of year - but I find it curious. Does anyone else get the impression that they are moving the goalposts and trying different tactics - perhaps just to muddy the waters?
