It's all beige 'food'. No nutritional value whatsoever and throw in the booze and fags and it's quite an expensive trolley. They then complain they can't afford to eat healthily.
I don't usually shop there, but I popped into Asda the other day, and it embodies this lifestyle. Trolleys of crisps, biscuits, fizzy drinks, unhealthy frozen ready meals. The fruit and veg aisles merely just a gateway to it all.
