Traffic Calming Measure

This is something that happens in supermarkets; a two-seater with a trolley is wandering slowly and aimlessly down the aisles with a queue of other customers behind them. They seem apathetic and prepared to tolerate the slow progress, none of them apparently capable of saying “Excuse me” or “Can I just get by” or even “Get out of the way you fat, useless lump of shit!”
