Chick-Fil-A, Wendy's Get Top Drive-Thru Marks

A fast food industry magazine is giving top marks to Chick-Fil-A and Wendy's when it comes to service at the drive-thru.

QSR has released its study for six major restaurant chains. Chick-Fil-A led the flock, getting orders right 92% of the time, along with top scores for customer service and cleanliness. But Wendy's was the fastest by far, completing drive-thru orders in about two minutes and ten seconds. That's 20 seconds faster than Taco Bell, which ranked number two for speed.

Burger King had the lowest scores in both accuracy and speed, getting orders right 83% of the time and taking more than 3.5 minutes on average. McDonald's and the burger chain Krystal finished in the middle of the group for most categories.
