"Personally, I'm not sure that legality or otherwise does make a 'big" difference, if IKEA and Dobbies are continuing to receive footfall far in excess of what could be accounted for by Midlothian residents alone, as reported upthread."
It's possible many of these people are not even doing any shopping.
I spoke to someone recently who works in Primark in Dundee. She said she constantly has to disperse large groups of folk gathered in the store. Because people are not allowed to meet at home, they are meeting up with family and friends in shops instead.
As I said before, this Chrimbo malarky is going to be a great laugh and no mistake.
