WFAE All it takes for the Charlotte area to make a run on the grocery store during winter is a forecast of snow, no matter the amount. Perhaps that's why North Carolina was squeezed the hardest by the panic buying of gasoline following the Colonial Pipeline ransomware attack.

A toilet paper panic-buying stampede when Aldi store doors open in Sydney. This is ridiculous.. What triggers our impulse to panic buy?
