Needless to say, B&Q is on my blacklist now.
They've been tightening up for a while now.
Not sure why but I suspect the parking firm get their money from the tickets issued and as a result they're getting tougher. You used to be allowed to park in that car park when using the gym but that stopped a while ago. I couldn't work out if it was the fault of the gym or the fault of BandQ.
I agree though, to some extent, with the blacklist - I wouldn't go as far as never using them but every time someone makes something less convient I reach for my mouse to shop online a bit more!
