A manifestation of this law played itself out earlier today in Intermarche stores throughout France. The BBC reports:
Intermarché supermarkets offered a 70% discount on Nutella, bringing the price down from €4.50 (£3.90) to €1.40. But police were called when people began fighting and pushing one another. "They are like animals. A woman had her hair pulled, an elderly lady took a box on her head, another had a bloody hand," one customer told French media. A member of staff at one Intermarché shop in central France told the regional newspaper Le Progrès: "We were trying to get in between the customers but they were pushing us."
