Sandy on Social Awareness.
Sounds like you go to a Waitrose. At my local Waitrose, the socially unaware have another name: Pensioners.
They must always have their shopping trolleys right next to them which means blocking off access to at least two sections of shelving for everyone else. The reason is quite natural: someone may walk off with their trolley-full of unbought items.
And God forbid, you have to go to a Waitrose on a Friday at midday. It is impossible to find a parking spot, not because there isn’t one available, but because pensioners are ambling about as if it is a Sunday drive.
(I call Fridays at the local Waitrose the Day of the Dead, as there is a general aimless shuffling about that I have previously only ever seen in George Romero films.)
