Jan Polanik accused 20 local Dunkin’ Donuts of grand deception.

It turns out it’s all about how you order a bagel.

If you ask for a bagel with butter, you will get a butter substitute.

A spokesperson told the Boston Globe that customers will only get real butter if they ask for it on the side.

This is because Dunkin’ workers keep the butter packets refrigerated and the margarine at room temperature, so it’s easily spreadable.

It’s unclear how much money the man won in the lawsuit.
