The NHL’s St. Louis Blues and Chicago Blackhawks aren’t just regional rivals; the two teams are currently playing each other in the first round of the Stanley Cup playoffs. So you can understand why some St. Louis residents might be less-than-thrilled that their local Dunkin’ Donuts was serving up coffee in cups decorated with the Blackhawks logo.

Making matters worse, reports KMOV-TV, the cups boast that Dunkin’ Donuts is “The official coffee of the Chicago Blackhawks.”

The unexpected coffee holders, of course, did not exactly go over well with Blue fans in the area.

KMOV took a few of the cups to the Scottrade Center before the game started on Wednesday, asking fans their thoughts.

“That’s disgusting. They can’t do that here,” one fan said.

Dunkin’ Donuts chalked up the mishap to a simple shipping error, noting that the store in question stopped using the cups almost immediately.

“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.”
