According to a new study, Chick-fil-A has the slowest drive-thru in the country.

The study, which tracked the 10 major U.S. fast-food chains, revealed Chick-fil-A has an average drive-thru wait time of eight minutes and 29 seconds, which includes time spent waiting in line and then getting your food, according to a report by Intouch Insight, an IT customer service company, and QSR, a restaurant magazine.

KFC earned the top spot with an average of five minutes and two seconds.

However, there is a catch.

The study is based on popularity, which means a reason for the slow time is Chick-fil-A averages 4.74 cars in its drive-thru, which is much higher than the average of 2.76 cars among the 10 chains.

If the study were considering quickest average based on number of cars, Chick-fil-A is first with an average of one minute and 47 seconds in that box.

The study was based on 1,500 drive-thru orders at the top chains across the U.S.

The list of restaurants with Chick-fil-A: 

• Wendy’s
• Burger King
• Dunkin’
• McDonald’s
• Arby’s
• Carl’s Jr.
• Hardee’s
• Taco Bell
• KFC

KFC, by the way, had the quickest drive-thru time but only an average of two cars – nearly three fewer than Chick-fil-A.

Accuracy

McDonald’s and Arby’s were most likely to execute a correct order at 89 percent accuracy.

Wendy’s came in last with 21 percent of orders inaccurate and last on drive-thru satisfaction – where Chick-fil-A was among the best.
