New York City's most ubiquitous chain has found itself in hot water for allegedly overcharging its customers around 70% of the time. Two lawsuits filed in New York and New Jersey claim that stores in both states erroneously charged customers state sales tax on items that weren't subject to those types of taxes. Two NJ customers claim to have been charged the state's 7% sales tax on bottled water and ground coffee, reports the Post, while customers in New York were charged sales tax for ground coffee (bottled water is subject to tax in New York State).

Small percentages can add up to huge numbers, though, and according to the suits, Dunkin Donuts made $4 million off New Jersey customers and a whopping $10 million off of customers in New York. A spokesperson for the Dunkin Donuts corporate office said it's looking into the allegations; next, we demand an explanation for this other assault on our intelligence.
