DENVER (CBS4)– A battle is heating up over fast food chain Chick-Fil-A and its desire to get cooking at Denver International Airport. The Denver City Council has delayed giving the restaurant a lease for the new location.

Some Denver City Council members are upset about the chain’s stance on gay marriage and are worried it could impact hiring and treatment of employees. Four city council members want to make sure there is no job discrimination at the city-owned airport.

“My research is really about the policies and practices, making sure that all families, including those like mine, are protected,” said Denver City Council member Robin Kniech.

Chick-Fil-A wants to move into the space currently occupied by Steak Escape on Concourse B. The chain’s president has voiced opinions in favor of traditional marriages as opposed to gay families and couples.

Kniech is the council’s first openly gay council member.

“I think the gay and lesbian community does feel concern about any organization that has, in the past, made reference to preventing families like theirs to being protected,” said Kniech.

Council member Jolon Clark is also pressing pause on the Chick-Fil-A deal until he’s satisfied the gay community is protected.

“The same thing that I’d like to hear from every business that comes through when we sign off on a contract that customers and employees would be treated fairly and equally and discrimination won’t be a part of how we do business in the city,” said Clark.
