Jan Polanik, a Dunkin' Donuts customer based in Worcester, MA, went to a local shop and asked for a bagel with butter. It turned out he was given a butter substitute - and so he sued. And locals might get free food because of him.
The The New York Times reports that Polanik sued 23 Dunkin' Donuts franchises in Massachusetts, because he paid 25 cents for butter and nobody told him he was getting a substitute. He has reportedly settled with Dunkin' Donuts, though the paperwork has yet to be approved, and the settlement is pretty great if you live in his area.
If the deal goes through, as many as 1,400 people can get up to three buttered muffins, bagels, or baked goods - with the real stuff, no substitute. Those people have to go to the 23 specific Dunkin' Donuts locations in Grafton, Leominster, Lowell, Millbury, Shrewsbury, Westborough, and Worcester. And all those stores will be required to use only butter for a year, and after that, they have to disclose whether they're using a substitute.
