Blackhawks cups inadvertently sent to St. Louis Dunkin' Donuts location

This is sure to leave a bitter taste in the mouths of some St. Louis Blues fans.

A shipping mix-up resulted in cups that read "Official coffee of the Chicago Blackhawks" being delivered to a St. Louis area Dunkin' Donuts location, according to KMOV, a local CBS affiliate.

The Kirkwood location sold coffee in the Blackhawks cups, which KMOV showed to Blues fans entering Game 1 of an opening-round series featuring the two rivals on Wednesday.

"That's disgusting. They can't do that here," said one fan.

The popular donut chain later released the following statement:

Due to an untimely shipping error from the regional distribution center. Being a local business owner and fan of the hometown team, the franchisee plans to switch out the cups as soon as they receive a new shipment.

Perhaps the cups were sent to St. Louis because they don't have one of their own quite yet.
