New study ranks Chick-fil-A with having the slowest drive-thru in the industry.

The chicken-centric chain was recently crowned as having America’s cleanest fast-food restaurants in a new survey, but at the same time, the Atlanta-based eatery was denounced for operating the slowest drive-thru in the industry, according to a separate poll.​​​​​​​

Chick-fil-A experienced a nationwide outage of its credit card system, according to an update on its Facebook page.

The issue stemmed from an outage at the fast-food restaurant's third-party vendor and lasted for about an hour before it was resolved. Chick-fil-A was unable to process any credit or debit card transactions during the outage, and the processing of mobile transactions through the company's app was also limited.

"We apologize for the inconvenience, but, for the moment, we are only accepting cash payments. This issue is affecting Chick-fil-A stores nationwide," a notice posted on a Frisco, Texas, restaurant's Facebook page said.
