Was just called the enemy in Costco

I live in Iowa on the border with Illinois, it's a mix of Chiefs, Bears, Packers, and Vikings fans so going to Costco is a strutting of the peacocks and I always wear Chiefs or Jayhawks gear. Tonight as we are rounding the dairy section an employee passes me and blurts out You know you're the enemy now. I stop and have a great big smile on my face and say being the Villian really does feel amazing. He and I both chuckle, but this seriously made my night.
