Great to see our middle class ABers being so judgemental and punching down.
While you may put your shopping in the boot of the car and drive it to your front door, not everyone has a car.
You may order on line and have it delivered to your door, not everyone has access to or the ability to do so.
You may even be a hero of the Green Revolution (like me) and carry your shopping bags home, unfortunately not everyone can be a fine physical specimen untouched by illness and/or human frailties.
So while I understand your perfectly rational anger at the sight of escaped shopping trollies strewn around the poorer parts of town that you're forced to drive through, spare a thought for the poor/enfeebled folk who 'steal' trollies to get their meagre morsels home. After all, it is Christmas. sob
