Talking about religion and politics can be dangerous among friends. It's doubly so for businesses.That double-edged sword became crystal clear last year after Chick-Fil-A's COO made comments about the chain's opposition to gay marriage. It sparked a massive backlash from the media, gay and lesbian couples, and even the mayor of Boston.
The controversy also helped the company shatter sales records after former Arkansas governor and Fox commentator Mike Huckabee organized a "Chick-Fil-A appreciation day."
Many other big companies in America are also religious, including some that might surprise you.
