Try as you might to get a space away from the madding crowd...the following is an example that seems to happen to me in Asda
So I parked here...as you can see VIRTUALLY EMPTY car park. The van on the left spoils the punchline but it WAS NOT there when I left!
...On return from my shopping. (note that I had parked over the chevrons to give more room in case a plonker came and parked in the bay next to me)...What I hadnt realised is that some tit would come and park in the small space besides me to the right...btw IT is NOT a space..
Should you worry?.....NOT if you take the wifes car on the shopping run!
