According to WILX, convenience is costing us more and more time in the fast food drive thru lane.

The average wait time from the speaker to the order window increased by 20 seconds in 2019, according to fast food industry publication QSR.

Of the 10 fast food chains QSR visited, Chick-fil-A was the slowest with an average time of 5 minutes and 23 seconds.

The lengthy waits come even as the company has started using iPads for taking orders and expanded to double drive thrus.

The fastest chain was Dunkin Donuts, coming in at about 3 minutes and 37 seconds.

QSR compiled its data on 10 chains from 1,503 visits across the country between June 1 and Aug. 1. Please click on the above link for more information.
