The big point is being missed here. The new “M&S Investment” means that M&S will no longer be selling their clothes here. National sales for their clothing falls every year but food sales keep the company afloat. Perhaps clothing will be now be centred on the internet.
As for access to the new site, it will make a busy site even busier. “Participant” makes the point that shoppers should move their car to a different part of the site, whenever they walk into a different store. I don’t think so. Imagine doing that at Chessy Oaks! You would be moving cars more than actually shopping.
Should there be another entrance to the new site in an attempt to ease congestion?
