Grumble Alert?

      I had occasion, today, to park outside Sainsbury's as being closer to wh ere I wanted/needed to be.
      There were significantly fewer Blue Badge slots than Blue badge holders; I had to seek a slot "wherever". I was relatively lucky in that I found one, while a Mobile Home was still cruising around slot seeking.
      I was forced to wonder how many more cars could have parked here; where, incidentally, I've little recollection of seeing many. sitting there.  I might have understood it, had it been a garden, or a bit of greenery of some type?
