$5.5 million

Pret A Manger, a sandwich shop with chains in several East Coast cities including New York, was hit with a $5.5 million class action lawsuit on Monday. Yee Ting Lau, a Pret A Manger customer, argues in the lawsuit that the company misleads its customers as to the real size of its sandwiches. As Gothamist wrote, “The shroud of deception, according to the suit, is a seemingly harmless cardboard casing — ‘lovingly handmade throughout the day,’ it reads — positioned in a way that obscures the actual size of the packaged wrap.” As a man whose primary motivations in life are “hunger” and “pettiness,” this is essentially the most important legal case of my lifetime.
