I'm all for free enterprise and for companies to expand and grow. But Tescos is fast becoming too big for its boots. It rides roughshot over councils by paying for developments which the councils wouldn't usually be able to afford. This sways councellors otherwise arbatory decisions to grant yet another Tescos megamarket or Tesos Express. It's rather like legal bribery.
I think you'll find, if you delve deeper, that this is the case.
