Chicago Blackhawks Cups Sent to St. Louis [PHOTO]

There are some very angry coffee drinkers in St. Louis and they have a great reason to be.

Dunkin' Donuts made a huge mistake that is making St. Louis Blues fans very, very angry.

The cups, pictured above, read, "Dunkin' Donuts: The official coffee of the Chicago Blackhawks."

St. Louis Blues fans went to get their cup of coffee and got stuck drinking from the Blackhawks cup. Pretty great mix up during the playoffs.

I have to say, as a Hawks fan, that is hilarious!
